A 17.5 kg cart is moving with a velocity of 7.65 m/s down a level hallway. A constant force of -10.0 N acts on the cart, and its velocity becomes 3.20 m/s. Assume that air resistance is negligible.
(a) What is the change in kinetic energy of the cart?
J
(b) How much work was done on the cart?
J
(c) How far did the cart move while the force acted?
m
