(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A superball with a mass of 83.6 g is dropped

from a height of 3.1 m. It rebounds to a height

of 2.5 m.

The acceleration of gravity is 9.8 m/s2.

What is the change in its linear momentum

during the collision with the floor? Answer in unit

of kg m/s.

2. Relevant equations

P=mV P=momentun m=mass V=velocity

changing P = F X changing time.

3. The attempt at a solution

the question asks the momentun during the collision with the floow, so P=mV

we know the m is 83.6 g . and do not know the velocity.

How do i get the velocity with above known vaule?
