Question

The cart in the image shown above begins at rest. The people on either side of the cart then pull as hard as possible.

Which direction will the cart move? Why?


A. The cart will move to the right because the more massive person can apply more force
B. The cart will move to the left because the less massive person can create more acceleration
C. The cart will not move because the forces are balanced

Answer 1

Answer: С

Explanation: A. This option is not necessarily correct. While it's true that the more massive person may be able to apply more force, the direction of the cart's motion depends on the net force, not just the force applied by one individual.

B. This option is also not necessarily correct. The acceleration depends on the net force applied to the cart, which is determined by both individuals pulling on it.

C. This option is likely the most accurate. If the people on either side of the cart are pulling with equal and opposite forces (assuming the forces are balanced), the net force on the cart would be zero, resulting in no acceleration or motion.
