A student strikes a block at the bottom of a ramp, giving it an initial speed vo up the ramp, as shown at right. There is friction between the ramp and the block as it slides a distance x up the ramp and then slides back down. On the dots below, which represent the block as it is sliding up the ramp and down the ramp, draw and label
the forces (not components) exerted on the block. Represent each force by a distinct arrow starting on, and
pointing away from, the dot. The dashed lines are drawn at the same angle as the surface of the ramp.
Up the Ramp
Down the Ramp
