3. John is performing an experiment in a Uwindsor lab. In this lab, John has two toy car's of mass m1 and m2 connected together to form a car of mass m whose velocity is v. While traveling a force causes these car's to separate, with the heavier car being at rest as a result. If John notes the kinetic energy of the moving car is 28 mv 2 what is the mass of the moving car? А. 0.018m В. 5.1m C. 0.011m D. 0.028m Е. 0.11m
