A barefoot field-goal kicker imparts a speed of 35 m/s to a football initially at rest. If the football has a mass of 0.39 kg and the time of contact with the ball is 0.038 s, what is the force exerted by the ball on the kicker’s foot?
I tried the formula F=(m(vf-vi))/change in time and got 359.210526316 but this was incorrect.
