Riders drop 36 m from the start until they hit a run-out at the bottom. If you give yourself a good push at the start, so that you begin your plunge moving at 3.0 m/s, how fast are you moving when you get to the bottom? The slide is steep and slippery, so assume that you can ignore friction and drag forces.
