Question #4dc5e

Answer 1

Newton's 2nd Law F=ma

Explanation:

Ok, this question is a little unclear, but here's what I think it's asking:

Starting with `F_1=m_1*a_1` this gives `F_1=m_1*14.9m/s^2`

Then, although it's not clear in the question, let's assume that the net force is going to remain the same after the mass is increased and the force is increased by a factor of 4.3.

This gives: `F_1/m_1=14.9m/s^2`

Then `{4.3F_1}/{13.5m_1}=a_2`

We know that `F_1/m_1=14.9m/s^2`, so we can substitute that into the equation we developed above:

`{4.3N}/{13.5kg}*14.9=4.74m/s^2`
