<h2>Magnitude of average force is 751.52 N</h2>
Explanation:
By Newtons second law force is rate of change of momentum.
Initial momentum = Mass x initial velocity
Mass = 58.5 g = 0.0585 kg
Initial velocity = +25 m/s
Initial momentum = 0.0585 x 25 = 1.4625 kgm/s
Final momentum = Mass x Final velocity
Mass = 58.5 g = 0.0585 kg
Final velocity = -22.5 m/s
Final momentum = 0.0585 x -22.5 = -1.3163 kgm/s
Change of momentum = Initial momentum - Final momentum = 1.4625 - (-1.3163)
Change of momentum = 2.48 kgm/s
Time = 3.33 ms = 0.0033 s
Magnitude of average force is 751.52 N
