How many complete revolutions does the wheel turn

Reference no: EM138469

Q1. A wheel is spinning clockwise at a 12.0 revolutions per second at t = 0. Because of friction in the bearings supporting the axle, the wheel slows down, losing 0.600 revolutions per second in angular velocity each second, until it comes to rest. How many complete revolutions does the wheel turn before coming to rest?

Q2. A rifle with a barrel length of 58 fires an 11 bullet with a horizontal speed of 370. The bullet strikes a block of wood and penetrates to a depth of 15.
