#### Using the equation for the final velocity in terms of masses and initial velocity

## What is the relation between initial velocity final velocity and time?

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v.

## How do you find velocity after a collision?

In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.

## How do you find velocity with mass and velocity?

How do I calculate escape velocity?Find the object’s mass in kilograms, M, and its radius in meters, R.Multiply M by the gravitational constant (6.674 x 10^{–}^{11}) and then by 2.Divide the result of step 2 by R.Raise the result of step 3 by 0.5. The result is the escape velocity.

## What is the formula to calculate initial velocity?

Initial velocity is 3.5. The equation is s = ut + 1/2at^2, where s – distance, u – inititial velocity, and a – acceleration.

## Can initial velocity be zero?

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

## What is the relationship between acceleration and velocity?

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.

## How do you find the final velocity of an inelastic collision?

Inelastic Collision FormulaV= Final velocity.M1= mass of the first object in kgs.M2= mas of the second object in kgs.V1= initial velocity of the first object in m/s.V2= initial velocity of the second object in m/s.

## What is the relation between mass and velocity?

Linear momentum is defined as the product of a system’s mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object’s mass and also its velocity. Thus the greater an object’s mass or the greater its velocity, the greater its momentum.

## How do you find velocity with force mass and distance?

Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so F_d = (m_ รท _2)_v^{2}. Substitute the measurements for force, distance and mass into the equation.

## Does mass affect velocity?

Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. Both bullets will strike the ground at the same time. The horizontal force applied does not affect the downward motion of the bullets — only gravity and friction (air resistance), which is the same for both bullets.

## What is the symbol of initial velocity and final velocity?

The symbol a stands for the acceleration of the object. And the symbol v stands for the velocity of the object; a subscript of i after the v (as in v_{i}) indicates that the velocity value is the initial velocity value and a subscript of f (as in v_{f}) indicates that the velocity value is the final velocity value.

## What is the symbol of initial velocity?

The symbol v_{} [vee nought] is called the initial velocity or the velocity a time t = 0. It is often thought of as the “first velocity” but this is a rather naive way to describe it.
