Homework Help: Physics

Can someone check and advise on this

potential energy of 2 tonne of water held 120m above a flood plain by a dam.

potential energy = 2032 kg (2 Tonne) x 9.81 ms x 120m

pe = 2392070.4 Joules

Convert to kilojoules

2392070.4 / 1000

pe = 2392 kJ (To four significant figures)

Many thanks
