Question
Train A is traveling at a constant speed va = 39 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 4 ft/sec relative to the train. The conductor perceives car B to move directly westward at 23 ft/sec. Find the velocity of A in ft/sec and find the velocity of conductor C relateive to the ground. UB Answers: VA = i ft/sec Vc = i ft/sec

Train A is traveling at a constant speed vA = 39 mi/hr while car B travels in a straight line along the road as shown at a constant speed VB. A conductor Cin the train begins to walk to the rear of the train car at a constant speed of vC/A = 4 ft/sec relative to the train. If the conductor perceives car B to move directly westward at vg/c = 23 ft/sec, how fast is the car traveling? UB B N
