Q. A rock stuck in the tread of a 59.0 cm diameter bicycle wheel has a tangential speed of 3.20 m/s. When the brakes are applied, the rock's tangential deceleration is 1.20 m/s^2

Q. A 202-kg projectile, fired with a speed of 123 m/s at a 53.0 angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally.

A.Determine the magnitude of the velocity of the third fragment immediately after the explosion.

B.Determine the direction of the velocity of the third fragment immediately after the explosion. (find theta above the horizontal)

C.Determine the energy released in the explosion.
