PLEASE EXPLAIN WHY YOU CHOSE EACH GRAPH

a) Which graph shows the FORCES that the bouncy ball and the door exert on each other? Explain reasoning

b) Which graph shows the MOMENTA of the bouncy ball and the door? Explain reasoning

c) Which graph shows the MOMENTA of the clay ball and the door? Explain reasoning

Consider the episode yoa fnood with the zombies a lew weeks back, where choosing the bouncy hall over the clay ball saved your life. The graphs helow show hova different quantitics for the balls and the doar vary in time during the collision. C door on door ball t ball t ball on ball on ball balF on deor on ball door on door

Explanation / Answer

a) As bouncy ball strike the door it start applying force on the dorr and same amount of force applied by the door on the ball but in opposite direction. Force on door will be along +x direction and force on ball will be along -x direction

Graph G represent this situation where forces are in equal magnitude at any instant and in opposite direction

b) Initially ball was moving along +x direction so it has positive momentua but after striking its direction changes but total momentum should remain smae

Graph A represent this situation

c) Initially clay ball have some positive momentum and after collision it stick with the door so both should move along positive direction and so both will have positive momentum along +x direction, in this case momentum of door will be greater than the ball

So no graph shows this situation in which ball also have some positive momentum
