Answer:
Explanation:
From Newton's law of motion, Force is equal to rate of change of momentum.
The initial velocity of the ball, u = 4.1 m/s
mass of the ball, m = 0.07 kg
During contact, velocity = 0
Time of contact, t = 72 ms = 72 × 10⁻³ s
Thus, net force applied to the ball during this collision is
