a vertical cable supports two vechicles a $1\mathrm{.}207$ kg minivan and a $1461$kg truck, with the minivan directly above the truck. The cable attached to the crane which lifts the vehicle with an acceleration $1\mathrm{.}30$m$/$s$^2/$ at one moment the minivan is moving at speed of $3\mathrm{.}00$m$/$s$.$ assume the cable does not stretch. How does the velocity and acceleration of the two vehicles compare?
