A cart coasts up a track and comes to rest. Its height is measured vertically from the same reference level at both positions.
| Quantity | Value |
|---|---|
| mass of cart | 0.80 kg |
| speed at start | 7.0 m/s |
| height at start | 0.6 m |
| height when it comes to rest | 2.5 m |
Use g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg.
Calculate the energy transferred to the surroundings as the cart coasts up the track.
