Can you please help me understand these problems.

Problem Statement | A 625 gram basketball bounces off the ground and we wish to find the impulse imparted on the ball by the ground during the collision. The ball hits the ground with a speed of 12.5 m/s, at angle of 35 with respect to the vertical. It bounces back at the same angle with respect to the vertical, but the speed of the ball is reduced by 20%.

(a) Draw a physical representation of the vector operation required to determine the impulse imparted on the ball. It should include representations of the initial moment, final momentum, and change in momentum. Be sure to carefully scale each vector relative to each other.

(b) Determine both the x and y components of the impulse vector imparted on the ball. Use that to find the magnitude of the impulse on the ball.

(c) In words describe how the ground imparts an impulse on the ball and the consequences of that impulse.

(d) What would Newton's 3rd law mean about the impulse imparted on the ground by the ball? Explain what this does to the ground?
