A wheel has an angular speed of 29 rev/s when it experiences a constant angular acceleration of 4rev/s2 which causes it to spin SLOWER. During this time the wheel completes 46 rev. Determine how long the wheel was experiencing this angular acceleration. Express your answer using appropriate mks units.
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.

A satellite is in a circular orbit around the Earth at an altitude of 2.24 x 106 m. (a) Find the period of the orbit. (Hint: Modify Kepler's third law so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 x 106 m, and the mass of the Earth is 5.98 x 1024 kg.) h (b) Find the speed of the satellite. km/s (c) Find the acceleration of the satellite....
