If a truck of mass 2.48e+3 kg on the road beside a frozen lake rescue a car of mass 790 kg that has skid onto the frictionless ice. The truck tows the car with a cable and we assume that the cable is massless, horizontal, and does not stretch). What is the tension in the cable when the first car is accelerating at 2.30~\text{m/s}^22.30 m/s 2 ?
