a ball is dropped twice off the same initial height. trial one bounces

a ball is dropped twice off the same initial height. trial one bounces back with a velocity of 3m/s and trial 2 bounces back with a velocity of 2m/s. the time the ball is in contact with the ground for trial 1 is 0.01s. are the impulses on the ball the same for both trials or is it less in trial 2???

What do you think, and why?

How would you define the Impulse?

change in momentum

Ok. What are the momentum changes in each case? And what is the other way of specifying impulse? (Working out speeds and times is easy, from the facts you have.)
