A ball weighing 0.5 kg, after an impact that lasts 0.02 s, acquires a velocity of 10 m / s. Determine the average impact force

To find out the average force of impact on the specified ball, we use the equality: F * t = m * Vp, from where we express: F = m * Vp / t (another way: F = m * a = m * (Vp – V0) / t = m * Vп / t).

Data: m is the mass of the specified ball (m = 0.5 kg); Vp – the speed acquired by the ball (Vp = 10 m / s); t – impact duration (t = 0.02 s).

Let’s make a calculation: F = m * Vp / t = 0.5 * 10 / 0.02 = 250 N.

Answer: The average impact force was supposed to be 250 N.
