Homework Statement
A Hollywood daredevil plans to jump the canyon shown in the figure on a motorcycle. There is a 15. m drop and the horizontal distance originally planned was 60. m but it turns out the canyon is really 69.4 m across. If he desires a 3.0-second flight time, what is the correct angle for his launch ramp (deg)?
Homework Equations
vx = vxo
x − xo = (vox)t
(vy) = (vyo) − gt
y − yo = (voy)t −(1/2)g t^2
Range =((vo^2)/g) sin(2θ)
The Attempt at a Solution
x − xo = (vox)t
69.4m = (vox)(3s)
23.13 m/s = vox
Range =((vo^2)/g) sin(2θ)
69.4m ={ (23.13^2 m/s)/9.81 m/s^2 } sin(2θ)
θ = error
