Q.
following the conservation of mechanical energy, we know at the top the skier has no KE, only PE(mgh) and at the bottom he has no PE, only KE (1/2mv^2) so solving for velocity, we get is KE to v=50m/s

Q.
Here we have the same situation, at the top we have nothing but potential energy (PE) and toward the bottom we have all KE, and if we set them equal to each other and solve for the velocity (v) we can find the final velocity at the bottom
