2. Pushing a rock: A worker is pushing a spherical rock of radius 0.5 meters and mass 1000 kilograms. She accidentally pushes the rock over the edge of a hill and loses control of it. At the moment she lets go of it the boulder is 1.0 meters from the bottom of the hill, which is at an angle of 5 degrees above the horizontal. When she lets go the center of mass of the boulder is moving at 1.0 m/s. How fast is it moving at the bottom of the hill? 1.0m 5°
