A ball is thrown against a wall and bounces back toward the thrower with the same speed as it had before hitting the wall. Does the velocity of the ball change in the process?
a) although the speed is the same, the direction has change . Therefore the velocity has change
b) The velocity is the same because the speed is the same
c) Without knowing the mass of the ball, the velocity is not determine
d) the velocity is now twice as large because the ball is going into opposite direction

Question

A ball is thrown against a wall and bounces back toward the thrower with the same speed as it had before hitting the wall. Does the velocity of the ball change in the process?
a) although the speed is the same, the direction has change . Therefore the velocity has change
b) The velocity is the same because the speed is the same
c) Without knowing the mass of the ball, the velocity is not determine
d) the velocity is now twice as large because the ball is going into opposite direction

Answer A because velocity is speed+direction so if the direction changes, the velocity changes.
