A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.70 104 m/s, and the radius of the orbit is5.00 106 m. A second satellite also has a circular orbit around this same planet. The orbit of this second satellite has a radius of8.40 106 m. What is the orbital speed of the second satellite? Show all work.
A rectagular boat is overloaded so that the water level (in fresh wateer) is just one centimeter (1.0cm) below the top of the boat, what is combined mass of all the people and the boat combined
At time t=0 a grinding wheel has an angular velocity of 28.0 rad/sec. It has the constant angular acceleration of 35.0 rad/sec^2 until a circuit breaker trips at time t=1.80. From then on, the wheel turns through an angle of 433 as it coasts to the s..
