Explanation / Answer

I am allowed to answer only 1 question at a time
Your 1st picture is not clear.
So I am answering this:

Tennis ball and wall,
impulse = area of curve
= area of trapezium
= 0.5*(b1+b2)*h
= 0.5*( 6ms + 2 ms )*Fmax
=0.5*(8*10^-3 s)* Fmax
= 4*10^-3*Fmax Ns

impulse also equal change in momentum
impulse = m*(Vf-Vi)
4*10^-3*Fmax = 0.063 Kg* (27 m/s - (-27m/s))
4*10^-3*Fmax = 0.063 Kg* 54 m/s
4*10^-3*Fmax = 3.402
Fmax = 850.5 N
Answer: 850.5 N
