## Homework Statement

A punter drops a ball from rest vertically 1 meter down onto his foot. The ball leaves the foot with a speed of 18m/s at an angle of 55##^{\circ}## above the horizontal. What is the impulse delivered by the foot (magnitude and direction)?[/B]

## Homework Equations

##p_b+p_f=p^{\prime}_{b}+p^{\prime}_{f}##

##v^2=v_{o}^2+2gh##

## The Attempt at a Solution

##\sqrt{2gh}=4.43m/s##

Would not one need to know the mass of the football to solve this problem? I

**find it uncomfortable and strange that the mass of the football is not included in this problem. Am I correct in this assertion?**
