At the moment of impact on a volleyball with a mass of 0.3 kg, a force of 120 N was applied for 0.05 s

At the moment of impact on a volleyball with a mass of 0.3 kg, a force of 120 N was applied for 0.05 s, determine the speed acquired by the ball.

Problem data: m (volleyball mass) = 0.3 kg; F (the force that acted on the volleyball) = 120 N; t (duration of exposure to force) = 0.05 s.
The speed acquired by the ball can be expressed from the equality: F * t = m * ΔV, whence ΔV = F * t / m.
Calculation: ΔV = 120 * 0.05 / 0.3 = 20 m / s.
Answer: After the impact, the volleyball began to move at a speed of 20 m / s.
