On a given, spherically symmetric planet, the acceleration of free fall at the surface is g . The radius of the planet is R . Consider a satellite moving about the planet in a circular orbit of radius 2R . A simple pendulum of length L and on planet earth has a period T . A uniform beam of mass M and length L is supported at its ends by two light vertical cords so that it makes an angle q with one of the cords, as shown in the sketch.
Someone cuts the right-hand cord.
A uniform disk is rolling along the ground with a constant speed v 0 . It encounters a plane inclined at an angle q with respect to the horizontal. The disk rolls without slipping up the plane. Dick, together with his suit, has a mass of 175 kg , and Jane, together with her suit, has a mass of 100 kg . Dick and Jane each pull on the rope and thereby draw closer together until they are only 5 meters apart.
