The footballer hit the ball with a force of 200 N. The ball weighing 0.4 kg after the footballer hit acquired a speed of 20 m / s. how long did the blow last?

These tasks: F (force with which the player hit the ball) = 200 N; m (ball mass) = 0.4 kg; V (the speed that the ball acquired after hitting) = 20 m / s.

The duration of the kick of a football player on the ball is determined by the formula: F * t = ΔP = m * V, whence t = m * V / F.

Let’s make a calculation: t = 0.4 * 20/200 = 0.04 s.

Answer: The kick of a football player on the ball lasted 0.04 s.
