1. A small car of mass 708 kg is parked behind
a small truck of mass 1797 kg on a level road.
The brakes of both the car and the truck are
off so that they are free to roll with negligible
friction. A 81 kg woman sitting on the tailgate
of the truck shoves the car away by exerting
a constant force on the car with her feet. The
car accelerates at 1.3 m/s2.
What is the acceleration of the truck?
Answer in units of m/s2.
2. Using F = ma, we know that she exerts a force of 920.4 N. But what would the acceleration of the truck be? I don't understand how to solve that problem.
