In a supermarket parking lot, an employee is pushing ten empty shopping carts, lined up in a straight line. The acceleration of the carts is 0.080 m/s2. The ground is level, and each cart has a mass of 25 kg.

(a) What is the net force acting on any one of the carts?
(b) Assuming friction is negligible, what is the force exerted by the fifth cart on the sixth cart?

  • Physics -

    (a) The net force acting on any single cart can be obtained from F = m a
    (b) The force acting on the sixth cart must be enough to accelerate carts 6 through 10. Use F = m a again, but the m is defferent.
