A spinning basketball is rotating clockwise at 5 revolutions/s. At 3 seconds, a player puts their hand on the ball and slows it down to a stop in one second. A.) What is the acceleration the player applied to the ball? B.) What is the total angular distance in degrees of the ball including the initial spinning and the angular distance while it was slowing? Please show all equations used and all your work.

As you finish listening to your favorite compact disc (CD), the CD in the player slows down to a stop. Assume that the CD spins down with a constant angular acceleration. A) If the CD rotates clockwise (let's take clockwise rotation as positive) at 500rpm (revolutions per minute) while the last song is playing, and then spins down to zero angular speed in 2.60s with constant angular acceleration, what is alpha_vec, the angular acceleration of the CD, as it spins...

A basketball is rotating at a constant one revolution per second on its way to the rim. Its diameter is 24.26 cm. a) What is the total angle the ball rotates through if it is in the air for 1.25 seconds? b) If started from rest in the players hand and it took 0.15 seconds to impart the rotation to the ball during the shot, what is the average angular acceleration?

A record is spinning at 60 rpm when the record player is turned off and friction brings the record to a stop. The record has a mass of 0.72 kg and a radius of 15cm. The moment of inertia for a disk rotating about its center is ½MR2. If the average frictional torque is 8.2 x 10-4 N•m, determine: a.How long does it take the record to come to a stop? b.How many revolutions does the record make while stopping?...
