A ball is moving with velocity 5 m/s in a direction which makes an angle of 30° with horizontal (i. e. with positive x-direction). This ball hits a vertical wall and gets reflected in a direction which makes an angle of 60° with the vertical (i. e. with positive y-direction) and moves with the same magnitude i. e. 5 m/s:
a. Find components of the initial and reflected velocities.
b. Show the vector representing the change in velocity of the ball.
c. Find the magnitude of the change in velocity.
