A daredevil decides to jump a canyon of width

14.6 m. To do so, he drives a motorcycle up
an incline sloped at an angle of 20.8

.
The acceleration of gravity is 9.8 m/s
2
.
What minimum speed must he have in order to clear the canyon?
Answer in units of m/s.

recall that the range of such a trajectory is
R = v^2/g sin2θ
You have θ and g, so set R=14.6 and solve for v
