A drone of mass 1.0kg moves upwards at a constant velocity of 5.0m/s. At 100m, all 4 of the drone's propellers stop.
Which below describes the subsequent motion of the drone?

A) The drone continues moving upwards with decreasing acceleration.
B) The drone continues moving upwards with increasing acceleration.
C) The drone immediately stops.
D) The drone immediately falls downwards with increasing acceleration.

the drone had zero acceleration when it was moving upwards. when the propellers stop, the weight of the drone would make a net force downwards and the drone would accelerate downwards.
but because the drone has inertia, would it continue moving upwards? is it option A or D?
