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?

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

c. magnitude and direction

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
