A place kicker must kick a football from a pint 35m from the goal. as a result , the ball must clear the crossbar, which is 3.05m high. when kicked, the ball leaves the ground with a speed of 20 m/s and at an angle of 54 to the horizontal.

a) To determine if the ball clears the crossbar, what is its height with respect to the crossbar when it reaches the plane of the crossbar?

b) what is the vertical velocity at the crossbar?
