Suppose you visit your local grocery store to do some shopping. You take the nearest shopping cart and start rolling. The following set of questions are based on the motion of the shopping cart. You start pushing the cart and reach constant velocity. Thus you are pushing the cart with zero force constant non-zero force O increasing force decreasing force
