An inclined plane makes an angle theta = 30° with the horizontal, as shown above. A solid sphere of radius R = 0.20 m and mass M = 1.8 kg is initially at rest in the position shown, such that the lowest point of the sphere is a vertical height h = 5 m above the base of the plane. The sphere is released and rolls down the plane without slipping. The moment of inertia of the sphere about an axis through its center is 2/5 MR 2. Determine the following for the sphere when it is at the bottom of the plane: i. Its linear velocity, ts translational kinetic energy, and Its rotational kinetic energy

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called
