2. A small disk of mass 2 kg is constrained to move in a circular path by a light rod of length 3. The linear velocity of the disk is 3 m/s. A piece of putty with a mass of 0.1 kg is dropped onto the disk. If the radius of the circular path remains constant, what is the linear velocity of the disk-putty system

Explanation:

Below is an attachment containing the solution.

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.
