A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a ramp of 61.8 degrees at a speed of 49 m/s. What would be the largest number of buses he can clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are 10.0 m long? Use g = 9.8 m/s?. Your answer should be in the form of an integer number (e.g., 3 buses, not 3.4 buses).
