Question

A place kicker must kick a football from a point 25.0 m (= 27.3 yd) from the goal, and the ball has to clear the crossbar, that is 3.05 m high. Whilst kicked, the ball leaves the ground with a speed of 16.8 m/s at an angle of 52.0o to the horizontal.

(a) By how much does the ball clear crossbar (if in fact it does)? Enter positive values if the ball clears and negative values if it falls below crossbar.

(b) What is a vertical velocity of the ball at the time it reaches the crossbar? Enter positive values if it is still rising and negative values if it is falling.
