Q. A place kicker must kick a football from a point 36.0 m (about 39.0 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 20.0 m/s at an angle of 53.0° to the horizontal.

Q. Illustrate what angular speed (in revolutions per minute) is needed for a centrifuge to produce an acceleration of 720 times the gravitational acceleration 9.8 m/s2 at a radius of 9.95 cm ?
