The kick of a football player imparted a speed of 10 m / s to a stationary ball weighing 500 g. Determine the force of the blow if it lasted 0.5s.
To find the value of the impact force of a given football player, we will use the equality: m * V = F * t, whence F = m * V / t.
The values of the variables: m is the mass of the previously stationary ball (m = 500 g = 0.5 kg); V is the speed imparted to the ball (V = 10 m / s); t – impact duration (t = 0.5 s).
Calculation: F = m * V / t = 0.5 * 10 / 0.5 = 10 N.
Answer: The force of impact on a previously stationary ball was 10 N.
