Question

Question: A child rides a tricycle, Tricycle 1, to the right while pushing another tricycle, Tricycle 2, that is being rode on by an older child. The total mass of Tricycle 2, tricycle plus older child, is three times the total mass of Tricycle 1, tricycle plus child. If the child is riding with enough force that the two tricycles accelerate to the right, what can be said for sure about the magnitudes of the forces on the tricycles?

1.) Explain in two sentences, why can't "The force on Tricycle 2 exerted by Tricycle 1 is larger in magnitude than the force on Tricycle 1 exerted by Tricycle 2" be the correct answer.

2.) Explain in two sentences, why can't "The force on Tricycle 2 exerted by Tricycle 1 is smaller in magnitude than the force on Tricycle 1 exerted by Tricycle 2" be the correct answer.

3.) Explain in two sentences, why can't " The force on Tricycle 2 exerted by Tricycle 1 could be larger or smaller depending on the size of the acceleration" be the correct answer.

For each question seperately, justify the reason why these answers are incorrect. Provide reasonable evidence.

Explanation / Answer

Form the given conditions, it is the action reaction pair. So the amount of force exerted on eachother is same in magnitude but opposite in direction.

In the above three cases, the magnitudes are equal.
