Homework Statement
What value(s) of θ will result in the block being accelerated 9.0m/s2 to the right?
Homework Equations
ƩFx = max
N = mg - P sin(θ)
The Attempt at a Solution
P cos(θ) - μkN = max
P cos(θ) - μk(mg - P sin(θ)) = max
P cos(θ) + μk P sin(θ) = max + μkmg
cos(θ) + μk sin(θ) = (1/P)(max + μkmg)
From here I can't find a trig identity that will help me isolate for theta.
