Unformatted text preview: 2 . We know that we have two equations for the trajectory of the ball: x = 100 t cos 45 y = 100 t sin 45 1 2 gt 2 + 3 Solving for when x = 400, we nd that t = 4 2. Plugging this into the equation for y , we nd that y 100(4 2) 1 21 2 32 . 2(4 2) 2 + 3 =112 . 2 ft Thus, we know that the ball does not clear the fence (nor does it come anywhere close, for that matter). 1...
