a) if we pick the zero-point of gravitational potential energy to be at the bottom of the ramp, then the total energy is E (initial) = 11.45 J b) the speed of the block when it returns to the rest position is V1 = 1.36 m/s c) when the block reaches a distance x2 = 0.1112 m beyond the rest point, its speed is V2 = 0.35 m/s
