. Car A is moving east at a speed of 40 mph relative to the ground. a) Car B is moving west at 50 mph relative to the ground. What is the relative velocity (speed and direction) of car B as seen by an observer in car A? Of car A as seen by an observer in car B? b) Answer the same questions if car B is moving east at 30 mph relative to the ground.
Solutions
Expert Solution
a) relative velocity of car B as seen by an observer in car A = 40 + 50
= 90 mph
direction = towards west
Of car A as seen by an observer in car B = 40 + 50
= 90 mph
direction = towards east
b) relative velocity of car B as seen by an observer in car A = 30 - 40
= 10 mph
direction = towards east
Of car A as seen by an observer in car B = 40 - 30
= 10 mph
direction = towards east

though is blowing at 90 mph, 40° south of east, relative to the
ground. The relative humidity of the air is 70%. How fast is the
airliner flying relative to the ground, and in what
direction?
