Assignment:
When a truck creeps along in traffic at a speed of 5 m/s, a man walks diagonally across the back of the truck at 3m/s. To a traffic helicopter in a stationary position above the road the road, the man's apparent motion is the superposition of these two motions; that is, his apparent velocity is the vector sum of the two given velocities. If the directions are shown as below, find the magnitude and direction.
Velocity man of truck = 3m/s (angle is 40 dg)
Velocity on road = 5 m/s (angle is 15 degrees)
