A penny sits 4.2 cm from the center of on a motionless record player with μs = 0.60. When the record player is turned on, what velocity will fling the penny off? When the record player is turned on, it accelerates at 1.0 m/s2. How many seconds after the record player is turned on will it reach that speed?

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?...

The OntarioTech rowing team is moving along at a steady speed of 17.86 m/s. The cox issues an order to increase the rate of speed of the boat and the boat uniformly accelerates to reach a final speed of 41.1 m/s. If the boat traveled a distance of 53 m before reaching the final velocity, what was the boat’s acceleration over that distance?
