Please answer both
A motocross hike drives off of a jump angled at 45 degree. When the bike leaves the jump, it has a speed of 20 m/n (about 40 mph). To ensure a smooth landing, the landing ramp nerds to be at the same angle as the hikes trajectory when it lands. If the landing ramp is 15 meters lower than the jump, what angle below the horizon should the Undoing ramp slope down? -30 degree -12 degree -58...
