A daredevil decides to jump a canyon of width 4.22 m. To do so, he drives a motorcycle up an incline sloped at an angle of 12.4◦. The acceleration of gravity is 9.8 m/s. What minimum speed must he have in order to clear the canyon? Answer in units of m/s.

Answer 1

Range = Vo^2*sin(2A)/g.
4.22 = Vo^2*sin(24.8)/9.8.
4.22 = Vo^2*0.0428, Vo^2 = 98.6, Vo = 9.93 m/s.
