According to Newton's First and Second Laws, what is always true when a net force is applied to an object?

Two objects of different masses are released from rest at the same height, one sliding down a frictionless incline and the other falling freely. According to $\text{Newton's First and Second Laws}$, what can be said about the speeds of the two masses at the bottom of their respective paths?

According to Newton's $1^{\text{st}}$ and $2^{\text{nd}}$ Laws, why does the bowling ball continue to move after Dr. Hewitt lifts it and gives it a push?
