Question
Train A is traveling at a constant speed vA = 30 mi/hr while car B travels in a straight line along the road as shown at a constant speed
Vp. A conductor C in the train begins to walk to the rear of the train car at a constant speed of vCA = 5 ft/sec relative to the train. If
the conductor perceives car B to move directly westward at vR/C = 25 ft/sec, how fast is the car traveling?
UB

Train A is traveling at a constant speed va = 30 mi/hr while car B travels in a straight line along the road as shown at a constant
speed vg. A conductor Cin the train begins to walk to the rear of the train car at a constant speed of 5 ft/sec relative to the train.
The conductor perceives car B to move directly westward at 25 ft/sec. Find the velocity of A in ft/sec and find the velocity of
conductor C relateive to the ground.
