A. Why couldn't the strong man move the box car with a force of 3000 Newtons? Make sure to include Newton's 2nd Law in your explanation.
B. What could be done to move the boxcar?
C. Another student claims that during the competition, the sum of the forces on the boxcar was 0 N. What evidence is the student using to make this claim? Be sure to explain your thinking.
