A wheel has an angular speed of 65 rev/s when it experiences a constant angular acceleration of 32 rev/s2 which causes it to spin FASTER. During this time the wheel completes 9 rev. Determine how long the wheel was experiencing this angular acceleration. Express your answer using appropriate mks units.

QUESTION 9 A model car initially at rest experiences a constant acceleration, reaching a speed of 8.50 m/s in a time of 4 s. What distance did the car move in this time, in units of meters? QUESTION 10 A satellite is moving around the Earth in a circular orbit with an angular speed of 4.7x10-4 rad/s. The angular speed is then increased at a constant angular acceleration to 5.3x104 rad/s. If this change in angular speed happened while the...
