a block of ice slides down a frictionless ramp at angle θ=30º while an ice worker pulls on the block (via a rope) with a force F that has a magnitude of 50 N and is directed up the ramp. As the block slides through distance d=0.50m along the ramp, its kinctic energy increases by 80J. How much greater would its kinetic energy have been if the rope had not been attached to the block?

A different robot begins pushing a 10kg box that was already moving at 0.5m/s [Right] along a surface with a coefficient of kinetic friction of 0.15. The robot pushes with only 3N [Right] of force. What is the acceleration of the box? Using the Work-Energy theorem, calculate how much work the robot does on the box accelerating it from 0.5m/s [Right] to 2m/s [Right].
