During a soccer game a ball (of mass 0.425 kg), which is initially at rest, is kicked by one of the players. The ball moves off at a speed of 26 m/s. Given that the impact lasted for 8.0 ms, what was the average force exerted on the ball? Show the solution and answer.

  • Mechanics -

    a = (V-Vo)/t = (0-26)/0.008s = 3250m/s^2

    F = m*a = 0.425 * 3250 = 1381.3 N.

  • Mechanics -

    Correction: a = (26-0)/0.008 = 3250m/s^2
