If some satellite has a M of 3830 kg and is in a circular- orbit 5.02 x 104 m above the surface of a planet. period of the orbit is 1.72 hours. The radius of the planet is 4.99 x 106 m. What is the weight of the satellite when at rest on the planet's surface?

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
