Homework Equations
Px = mVcostheta
Py = mVsintheta
Theta = tan-1(y/x)
Magnitude of P = (Px^2 + Py^2)^(1/2)
The Attempt at a Solution
Px = .165*2.84cos64.6 = .201 N*s
Py = .165*2.84sin64.6 = .4233 N*s
a) Theta2 = tan-1(-.4233/.201) = 64.6 degrees
b) (.201^2+.4233^2)^(1/2) = .4686 N*s
My work for part a may just have been luck or not needed but I obviously did something wrong since my answer in part b is wrong. Did I use wrong numbers for part b? Or am I supposed to calculate something else then find the magnitude?
