A softball having a mass of 0.25 kg is pitched at 114 km/h. By the time it reaches the plate, it may have slowed by 10 percent. Neglecting gravity, estimate the average force of air resistance during a pitch, if the distance between the plate and the pitcher is about 15 m.© BrainMass Inc. brainmass.com March 4, 2021, 6:13 pm ad1c9bdddf
F = m*a
a = delta(v)/delta(t)
The average velocity is [114 km/h + (0.90)(114 km/h)] / 2 ...
The solution is given equationally regarding the average force of air resistance.
