A 0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary for this change in velocity?

Use impulse-momentum: F_avg = Δp/Δt = mΔv/Δt.

Δp = 0.45 kg × 20.0 m/s = 9.0 kg·m/s.
F = 9.0 / 0.10 s = 90 N.

So an average force of 90 N (in the direction of the velocity change) was required.
