The solution to this problem does not use the required solution format. to solve this problem, simply draw the free -body diagrams for the following situations. in the free-body diagrams, include a vector indicating the direction of the net force (unless it is zero) and another vector indicating the direction of the object's acceleration (unless it is zero). include the force vectors (magnitude and direction) but do not include separate arrows for their components. a) you are riding a bicycle down a hill while applying the brakes and skidding to a stop assume that air resistance is negligible, but friction is not. b) you jump off a bridge with a bungee cord attached to your ankle, and the cord stretches. assume air resistance is negligible c) a rocket is accelerating straight up through the earth's atmosphere. assume that air resistance is not negligible d) a meteoroid moves downward through the earth's atmosphere. its speed is decreasing. assume that air resistance is not negligible
