A girl of mass throws a ball of against a wall. The ball strikes the wall horizontally and it bounces back with this same speed. Is there a change in momentum of the ball?
a) yes
b) no
c) depends on speed of ball
d) depends on mass of ball
Homework Answers
Momentum is given by,
p = mv
hence, since the velocity of ball changes due to change in direction of the ball after bouncing back, momentum of the ball will change. Hence there is a change in momentum and the answer would be yes.
