N identical beads (mass m) can move along the ring of radius R. Each bead is connected to the one behind it and to the one in front of it by a spring of constant k. Find all normal frequencies.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
