Data: M – Mass of the specified tennis ball (m = 100 g = 0.1 kg); F is the impact force of the tennis player (F = 300 H); T is the duration of the blow (T = 0.1 s).
To find out the speed acquired by the specified tennis ball, consider the equality: f * T = M * Vx, where we express: Vx = f * T / m.
Perform the calculation: Vx = f * T / M = 300 * 0.1 / 0.1 = 300 m / s.
Answer: The specified tennis ball has acquired a speed of 300 m / s.
