1. The problem statement, all variables and given/known data A ball is ikicked off a 100.0 m canyon at an angle of 30.0 degrees above the horizontal with a velocity of 24.0 m/s. What maximum height does it reach above the canyon floor? 2. Relevant equations WNC = KE + PE 3. The attempt at a solution WNC = 1/2mvf^2 - 1/2mvi^2 + mghf - mghi 1/2mvi^2 + mghi = 1/2mvf^2 + mghf I'm not sure what to do with the 30.0 degree angle?
