With what force did they hit the ball with a mass of 250g, if its acceleration at the moment of impact is 12m / s2.

To find the required force of impact on the ball, we will use Newton’s second law: F = m * a.

The values of the variables: m is the mass of the ball (m = 250 g = 0.25 kg); a (acceleration at the moment of impact) = 12 m / s2.

Let’s make a calculation: F = m * a = 0.25 * 12 = 3 N.

Answer: The ball was hit with a force of 3 N.
