## Homework Statement

A barefoot field-goal kicker imparts a speed

of 37 m/s to a football initially at rest.

If the football has a mass of 0.41 kg and the

time of contact with the ball is 0.012 s, what

is the force exerted by the ball on the kicker’s

foot?

Answer in units of N.

## Homework Equations

F=ma

## The Attempt at a Solution

F= .41 * (37/.012) = 1264.166667 N

Answer was wrong, wouldn't this obey newtons third law?

Or am I overlooking something obvious??? Please help!
