A vertical cable supports two vehicles, a 1,207 kg convertible and a 1,461 kg van, with the convertible directly above the van. The cable is attached to a crane, which lifts the vehicles with an acceleration 1.26 m/s. At one moment the convertible is moving at a speed of 3.40 m/s. Assume the cable does not stretch. (a) How do the velocity and acceleration of the two vehicles compare? O At any instant the van has a higher velocity compared to that of the convertible and at all instants they have the same acceleration. At any instant the van has a lower velocity compared to that of the convertible and at all instants they have the same acceleration. At any instant they have the same velocity and at all instants they have the same acceleration. (b) What is the tension, Tower (in N) in the cable between the convertible and the van? N (c) What is the tension, Tupper (in N) in the cable above the convertible? N
