Question 3: Comparing Elastic and Inelastic Collisions Part A
How do the changes in velocity of ball 1 and ball 2 compare in elastic (bouncy) and inelastic (sticky) collisions? Use these
number lines to help you decide.

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

Cathy is pedaling down a steep hill on her bicycle and wants to be able to coast up the next hill, which is 25 meters high, without pedaling. cathy and her bicycle have a mass of 75 kg. assuming her bicycle is 100% efficient, what would her speed have to be?
