2014 F = ma Exam — Question 25

25. A block with mass m is released from rest at the top of a frictionless ramp. The block starts at a height h1 above the base of the ramp, slides down the ramp, and then up a second ramp. The coeﬃcient of kinetic friction between the block and the second ramp is µk. If both ramps make an angle of θ with the horizontal, to what height h2 above the base of the second ramp will the block rise? — Source: Question 25, 2014 F = ma Exam, © 2014 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
