A motocross bike drives off of a jump angled at 45°. When the bike leaves the jump, it
has a speed of 20 m/s (about 40 mph). To ensure a smooth landing, the landing ramp
needs to be at the same angle as the bikes trajectory when it lands. If the landing ramp is 15 meters lower than the jump, what angle below the horizon should the landing ramp slope down?
(a) -30°
(b) -12°
(c) -58°
(d) -45°
