Acliff diver positions herself on the edge of a cliff that angles downward towards the edge. the length of the top of the cliff is 41.0 m and the angle of the cliff is 20.0 degrees below the horizontal. the cliff diver runs toward the edge at a constant speed, and reaches the edge with a time of 5.71 s. after running straight off the edge without jumping up, the diver falls h=26.0 m before hitting the water. after leaving the edge of the cliff how much time does the diver take to get to the water? how far horizontally does the diver travel from the cliff face before hitting the water? remember that the angle is at a downward slope to the right.
