The pool is above sea level.
5.0 kg of water is pumped from sea level into the pool.
The water gains 196 J of gravitational potential energy.
gravitational field strength = 9.8 N/kg
Calculate the height of the pool above sea level. Use the
equation:
gravitational potential energy
height =
mass × gravitational field strength
[2 marks]
Height = m
