Correct answer to the question A student strikes a block at the bottom of a ramp, giving it an initial speed vo up the ramp, as shown at right. Marbles from all 3 of these ramps traveled the same distance. If the block had been originally at rest and is free to move, what is its resulting speed? It passes through a 2.0 m rough section of the surface where friction is not negligible, and the coefficient of kinetic friction between the block and the rough section k is 0.2. KA
