a baby carriage is sitting at the top of a hill that is 21m high. The carriage with the baby weighs 12kg. The carriage has ________________ energy.Calculate it.

Answer 1

• Height=h=21m
• Mass=m=12kg

`\\ \rm\longmapsto P.E=mgh`

`\\ \rm\longmapsto P.E=12(10)(21)`

`\\ \rm\longmapsto P.E=120(21)`

`\\ \rm\longmapsto P.E=2520J`
