Question

A shopping cart slows as it moves along a level floor. Which statement describes the energies of the cart?

(1) The kinetic energy increases and the gravitational potential energy remains the same.
(2) The kinetic energy increases and the gravitational potential energy decreases.
(3) The kinetic energy decreases and the gravitational potential energy remains the same.
(4) The kinetic energy decreases and the gravitational potential energy increases.

Answer 1

When a shopping cart slows as it moves along a level floor, the best description of the energy of the cart would be that "(3) The kinetic energy decreases and the gravitational potential energy remains the same."

Answer 2

When a shopping cart slows as it moves along a level floor, the best description of the energy of the cart would be that "(3) The kinetic energy decreases and the gravitational potential energy remains the same."
