Sin contest question from 2003-- Can't figure this question... it's exam review! help the questions is: A kid is 5m from a fence that is 4 m high. He throws a ball @ 45 degrees from the horizontal which just grazes the fence. How far beyond the fence does the ball land? You may assume that the ball was thrown from the same level as the ground on the far side of the fence When the question says " just grazes the fence" how high does that mean and is there a mistake because the initial velocity is not given?
