A block is released from rest at height d=40 cm and slides down a frictionless ramp and onto a first plateau, which has length d and where the coefficient of kinetic friction is 0.50. If the block is still moving, it then slides down a second frictionless ramp through height d/2 and where the coefficient of kinetic friction is again 0.50. If the block is still moving, it then slides up a frictionless ramp until it (momentarily) stops. Where does the block stop? If its final stop is on a plateau, state which one and give the distance L from the left edge of that plateau. If the block reaches the ramp, give the height H above the lower plateau where it momentarily stops.

in there you say a frictionless ramp with a coefficient of kinetic friction of .5. if it is frictionless it wouldnt have one...

Kinetic potential= mv² (mass cases velocity squared) skill potential + Kinetic potential + warmth misplaced to friction = entire potential What this quite skill is that on each and every occasion the spring is pulled back totally, all the potential is skill, and none is kinetic. as quickly as the spring is launched, the aptitude potential is being converted into kinetic potential. Kinetic potential is the potential of stream. a million/2 way in the process the launch, while the vehicle has the main kinetic potential, it has the least skill potential. the finished volume of potential is the comparable, in spite of the incontrovertible fact that it somewhat is converted from skill to kinetic. in spite of the incontrovertible fact that, potential is misplaced as a results of friction. Friction reasons potential to be converted to warmth. on the tip, while the vehicle includes a end, all potential has been misplaced to friction and converted to warmth.
