Question

In each of the cases shown below, the direction of motion of the object is indicated by the velocity vector v. One or more forces act on the object as shown in the diagram. How will the velocity of the object change in each case in the direction of motion? Assume the forces shown remain constant in magnitude and direction.

For a), b), and c): Choose one:

(A) magnitude will increase, direction will be the same

(B) magnitude will decrease, direction will be the same    

(C) magnitude will increase, direction will change

(D) magnitude will decrease, direction will change

(E) no change in magnitude or direction

Explanation / Answer
