14. A slower-moving car is traveling behind a faster-moving bus. The velocitics of the two vehicles are as follows: Vcc = velocity of the Car relative to the Ground = +12 m/s VBG = vclocity of the Bus relative to the Ground = +16 m/s A passenger on the bus gets up and walks toward the front of the bus with a velocity of Vr. where Vpn = velocity of the Passenger relative to the Bus = +2 m/s. What is Vpc, the velocity of the Passenger relative to the Car? (a) +2 m/s + 16 m/s + 12 m/s = +30 m/s (b) -2 m/s + 16 m/s + 12 m/s = +26 m/s (c) +2 m/s + 16 m/s 12 m/s = +6 m/s %3D (d) -2 m/s + 16 m/s – 12 m/s = +2 m/s
