One Dimensional Collisions: Analyzing Impulse and Average Forces

[Cwhitlatch32]

Homework Statement

a ball of mass 2.50kg is thrown upward. it leaves the hand w/ an upward velocity of 19.6m/s.
(on the way down now )after the ball hits the throwers hand it comes to rest in .20s
a. What is the impulse exerted on the ball?
b. What is the average net force on the ball during this time?
c. What is the average force exerted by the hand on the ball?

Homework Equations

Impulse=change in momentum

The Attempt at a Solution

Havent been able to make an attempt to confused.

Your Relevant Equation gives you a big hint. Looks like you want to find the change in momentum as the ball is caught.

You must make some attempt or at least show what you know and where your confusion lies or your question will be marked for deletion!

 

[nil1996]

for the first question you have to just find the momentum before collision and momentum after collision with the hand and subtract.
For the second,Average force=(Change in momentum /time taken for the change)
