Question

A cricket ball of mass 800g has momentum of 20kg m/s , calculate velocity of ball?

Answer 1

The velocity is 25 m/s in the direction of the momentum.

Step-by-step explanation:

Momentum is directly proportional to an object's mass and velocity. Given its mass, knowing the momentum allows you to determine the velocity. Using the appropriate units, the velocity is as follows:

`p=mv\implies v=(p)/(m)=(20kg(m)/(s))/(0.8kg)=25(m)/(s)`

The velocity is 25 m/s in the direction of the momentum.

Answer 2

P=MV

V=P/M
