... In the case of the whirling can, it is a common misconception to state that a centrifugal force pulls outward on the can. In fact, when the string breaks the can goes off in a tangential straight-line path because no force acts on it. So when you swing a tin can in a circular path, there is no force ...

... downward. From Newton’s second law, if an object is accelerating downward, the total force on the object must be downward. The answer is C because only there is the downward force (the weight of the car) greater than the upward force (the normal force on the car) so that the total force is downward. ...
