Answer:
Reflection of sound waves also leads to echoes. Echoes are different than reverberations. Echoes occur when a reflected sound wave reaches the ear more than 0.1 seconds after the original sound wave was heard. ... Reflection of sound waves off of curved surfaces leads to a more interesting phenomenon.
Impulse = change in momentum
J = mΔv = (65.1 kg)(1.82 m/s) = 118.5 kg-m/s
the floor exerts the normal force, which is equal to the player's weight
N = W = mg = (65.1 kg)(9.8 m/s²)
Impulse = average force * time applied
118.5 kg-m/s = F (0.450 s)
