11. In a grocery store, you push a 14.5 kg shopping cart. It is initially rolling at a constant speed of 2.0 m/s. You push on it in the direction opposite to its motion exerting a force of 12.0 N. (Ignore friction for
all parts of this problem.)
a. Draw a free body diagram for the cart when you start pushing in the direction opposite to its
motion.
b. Write Newton's second law in component form for the process.
C. Assuming you push the cart exerting constant force for a while, how far will it travel in 3
seconds?
