a) A 50.0 gram ball is held 1.2m above the ground. If the ball is dropped what is its kinetic energy when it has fallen to 0.80m above the ground?

b) A ball in uniform circular motion with a radius of 0.80m has a centripetal acceleration of 8.45 m/s2. What is its linear velocity?

c) A ball in uniform circular motion with a centripetal acceleration of 12.0 m/s2 has an angular velocity of 3.00 rad/s. What would be the radius of this circular motion?
