A place kicker should kick a football from a point 34 m (about 37 yd) from the goal, and the ball should clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground by a speed of 26 m/s at an angle of 45 degrees to the horizontal.

a) By how much does the ball clear or fall short of clearing the crossbar? The acceleration of gravity is 9.8 m/s^2. Answer in units of m.

b) To decide if the ball approaches the crossbar while still rising or while falling, what is its vertical velocity at the crossbar? Answer in units of m/s.
