a barefoot field-goal kicker imparts a speed of 30 m/s to a football at rest. If the football has a mass of 0.50 kg and time of contact with the football is 0.0025 s, what is the force exerted on the foot?
Impulse = (Force)x(Time) = Momentum Change
= 15 kg*m/s
Solve for the Force, which will be in Newtons (kg m/s^2)
