An object is dropped from a height of 57.1 meters. Determine how long it takes the object to hit the ground. Ignore air resistance.
Use d=v;(t) + 1/2 (a)(t2)

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
