Question 21

A motorised cable system raises a weather sensor along a vertical mast. The sensor has a mass of 7500 g and is initially 1.2 m above the ground. Its gravitational potential energy increases by 600 J. Use g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg.

Calculate the final height of the sensor above the ground.
