On a single, light, vertical cable that does not stretch, a crane is lifting a 1,207-kg Ferrari and, below it, a 1,461-kg BMW Z8. The Ferrari is moving upward with speed 3.70 m/s and acceleration 1.50 m/s2.

(a) How do the velocity and acceleration of the BMW compare with those of the Ferrari? At any instant they have the same velocity and at all instants they have the same acceleration. At any instant the BMW Z8 has a higher velocity compared to that of the Ferrari and at all instants they have the same acceleration. At any instant the BMW Z8 has a lower velocity compared to that of the Ferrari and at all instants they have the same acceleration.

(b) Find the tension in the cable between the BMW and the Ferrari. N

(c) Find the tension in the cable above the Ferrari. N
