A wheel 1 meter in diameter is rotating at 100 revolutions per minute without slipping along a level stretch of road and passes mile marker 0 at 12:00 noon. it continues past mile marker 0 for 10 minutes and then has a period of angular acceleration of 2.5x10^-2 radians per second^2 for a period of 90 seconds. After the 90 sec acceleration period, the wheel rolls on for 1 hour. At the end of the hour the wheel undergoes a deceleration of 1.5x10^-2 radians per sec^2 until it stops. How far is the wheel in km from mile marker 0? what time is it when it stops?
