Exercise:
Spymaster Paul flying a constant speed horizontally in a low-flying helicopter wants to drop secret documents o his contact's open car which is travelling pq on a level highway pq.m below. When he sees the car in front of him at an angle of grad below the horizontal he drops the documents and strikes. Calculate the speed of the helicopter.

Solution:
The secret documents take a time of t sqrtfracsg pqs until they hit the car pqm below. Initially the car is s_x fracs_ytanalpha pq.m horizontally aprat from the helicopter. Within the pqs the documents have to travel the distance s_x i.e. need an additional speed of: v_x fracs_xt pqpq. The total speed of the helicopter is therefore pq
