A skateboard track has a horizontal segment followed by a ramp that declines at a 45° angle, as shown.
a) How long would the ramp need to be to give a landing for a skateboarder who launches from the horizontal segment at a velocity of 5.0 m/s?
b) If the initial velocity is doubled, what happens to the required length of the ramp?
