My Notes Ask Your Teacher A football punter accelerates a football from rest to a speed of 11 m/s during the time in which his toe is in contact with the ball (about 0.28 s). If the football has a mass of 0.45 kg, what average force does the punter exert on the ball? 6.84 Your response differs from the correct answer by more than 10%. Double check your calculations. N Need Help? Read ItExplanation / Answer
Sol1 ... 1 ton = 907 kg.
so 0.18*907 = 163.26 kg
g = 9.8 m per second squared
So weight = m*g = 163.26*9.8 = 1600 N
Sol 2...average force = change in momentum/ time
=( 0.45*11-0)/0.28
= 17.68 N
