HELP! block is released from rest and slides down a frictionless ramp inclined at 30' from the horizontal. When the block reache
s the bottom the block-Earth system has mechanical energy Eo The
experiment is repeated, but now horizontal and vertical forces of magnitude F are exerted on the block while it slides, as shown above. When the block reaches the bottom, the mechanical energy
of the block-Earth system
A) is greater than Eo
B)is equal to Eo
C)is less than Eo
D)cannot be determined without knowing
