## How do you find velocity without time?

Finding Initial Velocity without Time –

## How do you find the final velocity?

Basic Physics: Acceleration: Calculating The Final Velocity

## How do you find the velocity of a falling object without time?

In order to find the speed of an object, without knowing the time interval, we must know how long the object is going to fall for. VI = 0 m/s, since the object is at rest before it is released. d = distance between height of object and landing platform, or ground; (make sure your units are in meters).

## What is the formula for average velocity?

Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity. v = final velocity.

## What is the formula of displacement?

Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time. Here is a sample problem and its solution showing the use of this equation: An object is moving with a velocity of 5.0 m/s.

## What is the formula of force?

The formula for force says force is equal to mass (m) multiplied by acceleration (a). If you have any two of the three variables, you can solve for the third. Force is measured in Newtons (N), mass in kilograms (kg), and acceleration in meters per second squared ( m/s2 ).

## How do you find final velocity with acceleration and time?

## How far can you fall in 4 seconds?

Physics says you did not fall for 4 seconds. Falling for 4 seconds would give you a velocity of roughly 87mph, enough to kill the vast majority of people.

## What is the formula for projectile motion?

Projectile Motion Formulas. A projectile is an object that is given an initial velocity, and is acted on by gravity. Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2.
