A blоck оf mаss 10 kg mоves from position A to position B shown in the figure аbove. The speed of the block is 10 m/s аt A and 4.0 m/s at B. The work done by friction on the block as it moves from A to B is most nearly: A block sits at position A on a horizontal surface at the left. The horizontal distance from position A to the base of a ramp is labeled 3 meters. The ramp rises upward to the right and has a length of 4 meters. At the top of the ramp is a flat horizontal platform. Position B is on the raised platform, 2 meters to the right of the top of the ramp. The vertical height of the platform above the ground is labeled 2 meters.
