A student strikes a block at the bottom of a ramp, giving it an initial speed v, up the ramp, as shown at the right. There is friction between the ramp, as shown above. There is friction between the ramp and the block as it
slides a distance x up the ramp and then slides back down.
a. 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 on the
ramp. (double click on the drawing to edit it and draw your FBD's)
b. The block takes time to slide up the ramp a distance x. The block then takes time lam to slide back
down to the bottom of the camp, where it has speed y, Is greater than, equal to, or less than 1,?
In a clear, coherent paragraph-length response that may also contain figures and/or equations, explain your
reasoning. If you need to draw anything other than what you have shown in part (a) to assist in your response,
use the space below. Do NOT add anything to the figures in part (a).
