A 15.0-kg cart is moving with a velocity of 7.10 m/s down a level hallway. A constant force of -5.0 N acts on the cart and its velocity becomes 3.00 m/s.

(a) What is the change in kinetic energy of the cart?

(b) How much work was done on the cart?

(c) How far did the cart move while the force acted?
