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 ?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
