252The angle doesn't affect the final speed because the initial kinetic energy and potentialenergy change are the same regardless of direction, as long as the speed and height are the same.252The angle doesn't affect the final speed because the initial kinetic energy and potential energy change are the same regardless of direction, as long as the speed and height are the same.

254Yes, that makes sense. The final speed is sqrt(v0² + 2gh), independent of the launch angle.254Yes, that makes sense. The final speed is sqrt(v0² + 2gh), independent of the launch angle.
