Q. A placekicker must kick a football from a point 36.0 m 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 velocity of 20 m/s at an angle of 53.0 degress to the horizontal. by how much does the ball clear or fall short of clearing the cross bar?

Q. An object of mass 2.00 kg is held at a position A, a vertical height of 20.0 m above the ground. Point B is 8.00 m directly below A. Neglect air resistance and use g = 10.0 m/s.

What is the speed of the object at position B when it falls from position A?
