CHALLENGE QUESTION: A tiger leaps horizontally at 15 m/s across a 20 meter wide gorge on a trail. The edge she leaves is level with the edge she is aiming for. With front legs outstretched, she can grab and P claw her way up over the opposite ledge as long as she doesn't have to reach more than 1.5 meters above where she lands against the opposite wall of the gorge. Does she make it? Justify your answer.
