A Rope Runs Through a Pulley $3.05 \mathrm{~m}$ Off the Ground $0.61 \mathrm{~m}$

A rope runs through a pulley $3.05 \mathrm{~m}$ off the ground. One end hangs straight down and is attached to a car's engine that is being hoisted. The other end is attached $0.61 \mathrm{~m}$ off the ground to the rear bumper of another car. The car drives away at $4 \mathrm{~km} / \mathrm{h}$ . How fast, in $\mathrm{m} / \mathrm{s}$ , is the rope going through the pulley when the car's rear bumper is $4.88 \mathrm{~m}$ from being under the pulley? The rope is long enough so that the engine is between the ground and the pulley.
