1. A commercial ship is heading due North
at 12.0 km/hr but drifts westward at 5.0
km/hr. determine the magnitude and
direction of the resultant velocity of the
ship.
2. Find the resultant of the following
vectors.
A = 30 m at 30° with the x-axis
B = 20 m at 120° with the x-axis
C = 10 m at 225° with the x-axis.
1.
Find the magnitude of the resultant velocity from the Pythagorean theorem:
Find the direction of the resultant velocity from the geometry:
2.
Then it is the first Quadrant and
22.123 m at 66.25° with the x-axis
