The 0.2kg box below slides down a curved ramp, jumps

**Question**

The 0.2kg box below slides down a curved ramp, jumps a smallgap and lands on a flat platform. At the point on the rampshown it is 1.5m above the floor and it's speed is 2.0m/s. Atthe point shown on the platform the box is 0.4m above the floor andsliding at 4.2m/s.

a) How much energy has been converted to non-mechanical form(mostly thermal/internal energy) as the box moves between the twopoints shown?

b) Further down the ramp the object comes to rest. Howmuch energy has been converted to non-mechanical form as the boxmoves between the initial point shown and the point where the boxstops?

All solutions must be based on work and/or energymethods.
