Problem

A quadcopter of mass

2.0\,\text{kg}

hovers momentarily before its motors produce an upward thrust of

28\,\text{N}

. At the same instant, a steady wind exerts a force of

6.0\,\text{N}

due east and

4.0\,\text{N}

due north on the quadcopter. Neglecting air resistance other than the stated wind force, what is the magnitude of the quadcopter’s instantaneous acceleration? a)

4.2\,\text{m/s}^2

5.5\,\text{m/s}^2

7.8\,\text{m/s}^2

3.6\,\text{m/s}^2
