Question 6

A model drone of mass 1.2 kg is launched vertically upwards from rest from the ground. The drone's motor produces a constant vertical upward thrust of 18 N.

Assuming air resistance is negligible and taking g=9.8 m/s2g = 9.8\text{ m/s}^2g=9.8 m/s2, find the distance the drone has risen at t=4 st = 4\text{ s}t=4 s.
