A vertical cable supports two vehicles, a 1,207 kg plug-in hybrid and a 1,461 kg truck, with the plug-in hybrid directly above the truck. The cable is attached to a crane, which lifts the vehicles with an acceleration 1.23 m/s2. At one moment the plug-in hybrid is moving at a speed of 3.70 m/s. Assume the cable does not stretch. A) How do the velocity and acceleration of the two vehicles compare?
A. At any instant the pickup truck has a lower velocity compared to that of the plug-in hybrid and at all instants they have the same acceleration.
B. At any instant they have the same velocity and at all instants they have the same acceleration.
C. At any instant the pickup truck has a higher velocity compared to that of the plug-in hybrid and at all instants they have the same acceleration.
B) What is the tension, Tlower, (in N) in the cable between the plug-in hybrid and the pickup truck?
C) What is the tension, Tupper, (in N) in the cable above the plug-in hybrid?
