2. A 8.50 kg single seat soapbox car is rolling ahead of a 25.5 kg double seat soapbox car. If equal forces push the soapbox cars 1.80 m from rest, which of the following is true?

The kinetic energy of the single seat soapbox car is equal to the kinetic energy of the double seat soapbox car. The kinetic energy of the single seat soapbox car is greater than the kinetic energy of the double seat soapbox car. The kinetic energy of the single seat soapbox car is less than the kinetic energy of the double seat soapbox car. 3. In the figure provided, a particle is travelling along a closed vertical path.
