Question 57

A research drone of mass 15 kg15\text{ kg}15 kg is hovering stationary at a height of 420 m420\text{ m}420 m above the ground.

a.

State the two conditions necessary for the drone to remain in equilibrium.

[2]
b.

Calculate the change in gravitational potential energy of the drone as it rises from the ground to 420 m420\text{ m}420 m. (Take g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2)
