A drone is hovering at a constant height above the ground. The mass of the drone is 7 kg. The mass of the package is 3 kg. Calculate the upward force of the Drone.

To answer this Question we will use the equation derived from Newtons second law of motion,
F=ma or in this case W=mg as it is the mass of the object being accelerated by gracity, giving us it's weight
The acceleration downwards due to gravity at a rate of -9.81m/s^-2 The mass is the combined mass of the two objects: 7 + 3 = 10 kg
The weight is therefore = W = mg = 10 x 9.81 = - 98.1
As the question state the drone is hovering, the upwards force must be in equilibrium with the weight, giving us a final answer
W + F = 0
-98.1 + F = 0
F = 98.1 N
