Problem: A softball, of mass m= 0.20 kg, is pitched at a initial speed V = 28.8m/s. Due to air resistance, by the time it reaches home plate it has slowed by 10%. The distance between the plate and the pitcher is d=14m.
Part A: Calculate the average force of air resistance, F(air), that is exerted on the ball during its movement from the pitcher to the plate.
Please show each step to calculate the average force of air resistance.
