Solution:
By Newton's second law, \(F = \frac{\Delta p}{\Delta t} = \frac{mv}{t}\). Substituting the values, \(F = \frac{0.15\text{ kg} \times 20\text{ m/s}}{0.1\text{ s}} = 30\text{ N}\).
A player catches a ball of mass \(150\text{ g}\) in \(0.1\text{ s}\) moving with speed \(20\text{ m/s}\), then he experiences an average force of
