Question

A helicopter hovers 568 m above a field and 96 kJ of gravitational potential

energy is stored. Assuming g = 9.8 N/kg, find the helicopter's mass.

Answer 1

mass m = 17.2 kg.

Step-by-step explanation:

Use potential energy =m*g*h,

so,

m=potential energy/(g*h)

m=96000 J/(9.8*568) = 17.2 kg
