Unit 3: Motion in Two-Dimensions
Problem Set D
In an ideal punt, the football has a 'hangtime' (total time in the air) of 5.0 s. If a punter kicks the ball at an angle of 46.1 degrees with the horizontal, what must be the initial velocity (in m/s) of the ball to achieve this?
A discussion of the formulae for projectile motion, of the trajectory characteristics and of the basic strategy for solving such problems is provided on the Set D Overview Page.
Detailed information about and discussion of the strategies for solving non-horizontally launched projectile problems is provided online at The Physics Classroom.
