Homework Help: Physics

Posted by Sam on Monday, September 10, 2012 at 4:28pm.

A place kicker must kick a football from a point 29.0 m (= 31.7 yd) from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 17.8 m/s at an angle of 41.0o to the horizontal. By how much does the ball clear the crossbar (if in fact it does)? What is the vertical velocity of the ball at the time it reaches the crossbar?
