Problem

4.0\,\text{kg}

quadcopter hovers in still air when its rotors supply an upward thrust force. Suddenly a steady wind exerts a

6.0\,\text{N}

force toward the east. To give the quadcopter an acceleration of

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

upward and

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

toward the west, what thrust magnitude must the rotors now provide? (Assume the thrust can be directed vertically upward.) a)
