1. The problem statement, all variables and given/known data I have worked out at problem using the conservation of mechanical energy and the answer is correct. I have also worked out the problem using kinematics and got the same answer. My problem is that I can't wrap my brain around why it works out using the conservation of mechanical energy. Here is a statement of the problem (a graphic is attached as well with my solutions and some questions): "A motorcyclist is trying to leap across the canyon by driving horizontally off the cliff. When it leaves the cliff, the cycle has a speed of 38.0 m/s. Ignoring air resistance what is the speed when the driver strikes the ground on the other side?" 2. Relevant equations 1/2mvi^2 + mghi = 1/2mvf^2 + mghf vf^2 = vi^2 + 2gd 3. The attempt at a solution Please see attached w/ my included questions.
