The belt of one ramp moves at a constant speed such that a person who stands still on it leaves the ramp 64 s after getting on. clifford is in a real hurry, however, and skips the speed ramp. starting from rest with an acceleration of 0.37 m/s2, he cov- ers the same distance as the ramp does, but in one-fourth the time. what is the speed at which the belt of the ramp is moving?

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
