A of a) b) c) d)

How much kinetic energy was lost in the collision.

A 15cm radius wheel begins to rotate about its center at an angular speed 45 rads/s. It accelerates at 3.0 rad/s2 for 15s.

1. What is the final angular velocity and direction?
2. Find the velocity of a point on its rim.
3. How many revolutions does it make?
4. Find the average angular of the wheel from start to finish.

---- A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.7 s before coming to rest. A) If its initial angular speed was 3830 rpm , what is the magnitude of its angular deceleration? B) How...
