A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.65 x104 m/s, and the radius of the orbit is5.05 x 106 m. Asecond satellite also has a circular orbit around this same planet. The orbit of this second satellite has a radius of 8.80 x 106 m. What is the orbital speed of the second satellite?
An oscillator consists of a block attached to a spring (k = 475 N/m). At some time t, the position (measured from the system's equilibrium location), velocity, and acceleration of the block are x = 0.420 m, v = -11.9 m/s, and a = -139 m/s2. a)Calcula..
