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 = 1.27 m/s c) when the block reaches a distance x2 = 0.0412 m beyond the rest point, its speed is V2 = 1.07 m/s d) the block will come to a momentary halt when it reaches a distance X = 0.1001 m beyond the rest length of spring
