It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year-old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 69.3 N forward force on the wagon. There is a 31.3 N resistance force and the wagon and Casey have a combined weight of 316.0 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the acceleration of the wagon.

Ezra is occasionally asked to work the check-out line during his shifts at the Hy-Vee grocery store. During a recent lesson on Newton's Laws, he re-lived a memory from work. He wrote the following Physics problem and he wants you to solve it:

The handle of a paper grocery sack has a breaking strength of 321 N. Ezra loads the bag with 17.0-kg of soup cans. With what maximum acceleration can he lift the sack upward without breaking the handles?
