Solve Complex Sin Contest Question from 2003 | Exam Review Help

In summary, the question is asking for the distance beyond the fence that a ball lands after being thrown at a 45 degree angle from 5m away. The fence is 4m high and it is assumed that the ball was thrown from ground level on the far side of the fence. There is no mistake in the question not providing the initial velocity, as the height of the fence at the moment the ball grazes it is used instead.

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?

It probably means it's 4m high at the moment it goes over the fence. So it's not a mistake that the initial velocity is not given.

Edit: I'm sorry i just realized that this is 3+ year old post -_-
