How would the acceleration of a single shopping cart compare with the acceleration of a chain of three shopping carts if the same force acted on both?

To test the resilience of its bumper during low-speed collisions, a 4 060-kg automobile is driven into a brick wall. the car's bumper behaves like a spring with a force constant 8.00 106 n/m and compresses 3.72 cm as the car is brought to rest.

A 1500 kg car starts at rest and speeds up to 3.0 m/s. The gain in kinetic energy is 6750 J. We define efficiency as the ratio of output energy in this case kinetic energy) to input energy. If this car's efficiency is 0.30.
