f=ma
v^2/r
The Attempt at a Solution
Σfx = FNcos(θ) = (v^2/r)*m
Σfy = FNsin(θ) - mg = 0
FN = mg/sin(θ)
(mg/sin(θ))*cos(θ) = (v^2/r)*m
gcos(θ)*r = v^2*sin(θ)
r = v^2sin(θ)/gcos(θ) v = 150m/s θ = 38
r = 1793m
i have already solved this one a while ago and am reviewing for test tommorow and getting a bullocks answer that is not correct what on Earth am i doing wrong here?
