Question

On a day with a breeze blowing from the west at 8.5km/h, a remote control helicopter, facing north, takes off vertically from a level field at full power. It has a mass of 700g and the propeller generates 10N of thrust when running at full power. Once it reaches a height of 5m, the helicopter is tilted forward so that it maintains its height and accelerates towards the north. 10s later, the helicopter collides with a tree. How far away and in what direction is the tree from the place where the helicopter took off?
