Let us know about formula for height.

**What is Formula for Height**

Calculate the height of the object of interest by computing **“d * tan(theta)** ,” where “*” indicates multiplication and “tan” is the tangent to angle theta. For example, if theta is 50 degrees and d is 40 meters, then the height is 40 tan 50 = 47.7 meters, after rounding.

Also, how do you work out time with initial velocity and altitude?

Use the following formula to determine how far the projectile travels beyond its initial height, where V is the initial vertical velocity and T is the time it takes to reach its peak: **altitude = V * T +1/2 * -32.2 feet /s^2 * t^2** For example, if you had an initial vertical velocity of 32.14 ft/s and a time of one second, then . (Formula for Height)

Here, what is the initial velocity?

The initial velocity is the velocity at the **time interval t = 0** and is denoted by u. This is the velocity at which the motion starts.

Also know what is the formula for free fall? Free fall means that an object is falling freely, with no force acting on it except gravity, a defined constant, **g = -9.8 m/s ^{2}** . The distance the object falls, or height, h, is 1/2 gravity x square of the time it falls. Velocity is defined as gravity x time.

How do you find velocity with maximum height?

**How to find the maximum height of the projectile?**

- If α = 90°, the formula becomes simple: hmax = h + V₀² / (2 * g) and the flight time is the longest. ,
- If α = 45°, then the equation can be written as:…
- If α = 0°, then vertical velocity is equal to 0 (Vy = 0), and this is the case for horizontal projectile motion.

**How do you find the initial vertical velocity?**

The initial vertical velocity is the vertical component of the initial velocity: **V 0 y = V 0 sin 0 = (30.0 m/s)** sin 45° = 21.2 m/s. V0 y = V0 sin 0 = (30.0 m/s) sin 45° = 21.2 m/s. 10.0 m = (21.2 m/s) t – ( 4.90 m/s 2 ) t 2.

**What is the formula for flight time?**

The time of flight of an object, given the initial angle of launch and the initial velocity, is found: **T=2visinθg T = 2 vi sin** . The angle of reach is the angle at which the object must be launched to achieve a specific distance: =12sin−1(gdv2) = 1 2 sin − 1 ( gd v 2 ) .

**Is V initial or final velocity?**

It is represented by the letter U. Given below are three initial velocity formulas based on the equations of motion, if time, acceleration and velocity are known. is drawn as the initial velocity.

the formula for the initial velocity.

u | initial velocity |
---|---|

v | final velocity |

t | time taken |

s | displacement |

a | acceleration |

**When the initial velocity is zero?**

Well **if an object starts from rest** then its initial velocity will be zero but if it is already in motion then its initial velocity is greater than zero.

**What is the difference between initial velocity and final velocity?**

Initial velocity describes how fast an object travels when gravity first exerts a force on the object. On the other hand, final velocity is a vector quantity that measures the speed and direction of a moving body after reaching its maximum **acceleration** .

**What is the initial velocity in free fall?**

An object in free fall experiences an acceleration of -9.8 m/s/s. … If an object is dropped only from a higher height (as opposed to thrown), the initial velocity of the object is **0 m/** s . If an object is projected upwards in a completely perpendicular direction, it will slow down as it moves upwards.

**How do you calculate fall from height?**

Find the free fall distance using the equation **s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8** m. If you know the height the object is falling but don’t know the time it fell, you can use this calculator to find it too!

**What is the value of G?**

Its value is **9.8 m/ s ^{2}** on Earth. That is, the acceleration of gravity on the surface of the Earth at sea level is 9.8 m/s. is

^{2}. While discussing the acceleration of gravity, it was mentioned that the value of g is location dependent.

**What is the acceleration at maximum height?**

Its velocity is zero at the highest point of the projectile. At the highest point of the projectile, its **acceleration is zero** .

**How do you find the initial velocity given the maximum height?**

The maximum height of an object, given the initial projection angle and initial velocity, is found: **h=v2isin2θi2g h = vi 2 sin 2 i 2 g** .

**Can velocity be negative?**

**An object moving in a negative direction has** a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction of its motion (in this case, a positive acceleration).

**Can the initial velocity be zero?**

When a body starts moving from rest or changes its direction of motion, it is called initial velocity. We generally consider that the **initial velocity is equal to zero** (u=0), only when the object starts from rest. Normally at time (t=0), the initial velocity is zero.

**What is the initial vertical velocity?**

The vertical velocity component (v _{y} ) describes the **effect of velocity in** displacing the projectile vertically. …consider a projectile projected with an initial velocity of 60 m/s at an angle of 50° to the horizontal.

**How do you calculate time from max altitude?**

How to find the maximum height of the projectile?

- If α = 90°, the formula becomes simple: hmax = h + V₀² / (2 * g) and the flight time is the longest. ,
- If α = 45°, then the equation can be written as:…
- If α = 0°, then vertical velocity is equal to 0 (Vy = 0), and this is the case for horizontal projectile motion.

**How do we calculate time?**

The formula for time is given as **[time = distance speed]** . To calculate speed, the time formula would be cast as [speed = distance traveled time].

**What is the formula for free fall acceleration?**

An object in free fall will still have a weight, which is governed by the equation **W = mg** where W is the object’s weight, m is the object’s mass, and g is the acceleration due to gravity.

**Can the initial velocity be negative?**

Velocity. … Since the object’s final position (r final) can be either positive, negative, or zero, and can be either greater, smaller, or the same as the initial position (initial), the velocity can be positive, negative, or zero could. The sign of velocity depends on the coordinate system chosen to define the position.

**What is the difference between initial and final?**

The initial velocity is the velocity at time = t1, where t1 is the start of the time interval of interest, usually chosen as zero. The final velocity is the velocity at **time = t2** , where t2 is the end of the time interval of interest.

**Is the initial speed always zero?**

When a body starts moving from rest or changes its direction of motion, it is called initial velocity. We generally consider that the **initial velocity is equal to zero** (u=0), only when the object starts from rest. Normally at time (t=0), the initial velocity is zero.
