A 100g elastic ball hits the ground at an angle of -62 degrees with veloity 4.5m

Question

A 100g elastic ball hits the ground at an angle of -62 degrees with veloity 4.5m/s and rebounds at an angle of 75 degrees with a velocity of 4.2m/s.

1) Find the impulse delivered to the ball

2) Find the impulse delivered to the ground

3) If the interaction takes 0.085 s, what is the magnitude of the average force between the ball and the ground?

4) By how much does the velocity of the Earth change in this interaction? (Use M=6.4*10^24 kg for the mass of the planet and r= 6.0*10^6 m for its radius)

Please show all work, steps, and drawings (the drawing is the hardest part for me in this problem)
