A student has two ramps, both of which are at an angle 34°. Ramp 1 is frictionless and ramp 2 has friction. The student also has two blocks, one for each ramp. She pushes the blocks up the ramps with the same initial velocity. The block on ramp 2 only travels a fraction f = 0.570 as far as the block on ramp 1 before coming to a stop (i.e. d2 = 0.570*d1)
