Acliff diver positions herself on a cliff that angles downwards towards the edge. the length of the top of the cliff is 42.0 m and the angle of the cliff is î¸ = 20.0â° below the horizontal. the cliff diver runs towards the edge of the cliff with a constant speed, and she reaches the edge of the cliff in a time of 6.50 s. after running straight off the edge of the cliff (without jumping up), the diver falls h = 30.0 m before hitting the water. after leaving the edge of the cliff, how much time does the diver take to get to the water?

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.
