Newton's 2nd &3rd Laws

An Object Moving with constant acceleration, what can you say about the rate of change of the object's momentum?

An Object Moving with constant acceleration, what does Newton's second law says about the force acting on the object?

Determine the resultant force acting on the object, and draw the directions!
