9. A Ell kg crate sits at rest at the bottom of a 151] m long ramp that is inclined at 34.0\" above the horizontal. A constant horizontal force of 29a N is applied to the crate to push it up the ramp. While the crate is moving, the ramp exerts a constant frictional force on it that has a magnitude 55.0 N. [a]: 1ii'ii'hat is the total work done on the crate during its motion from the bottom to the too of the ramp? {h} Hoiiiir much time does it take the crate to travel to the top of the ramp? 111 A small block with mass d kg slides in a vertical circle of radius Fi=i.5 m on the inside of a circular track. During one of the resolutions of the block, when the block is at the bottom of its path; point A, the magnitude of the normal force exerted on the block by the track has a magnitude 3.95 N. In this same revolution, when the block reaches the top of its path, point B, the magnitude ofthe normal force exerted on the block has a magnitude of DEED N. How much work was done on the block by friction during the motion of the block from point A to point B
