A centrifuge in a medical laboratory rotates at an angular speed of 3500 rev/min. When switched off, it rotates 52.0 times before coming to rest. Find the constant angular acceleration of the centrifuge.
A ball is thrown in the air at an initial angle 35 degrees above the horizontal. It takes 4 seconds for the ball to hit the ground
Suppose you have a thin, uniform rod with a total mass of 3.00 kg and a total length of 2.00 m. By what percent- age does the moment of inertia decrease if you rotate it about a point located 20% (0.40 m) from one end, instead of at that end?
