This is what I thought.

I have the following integral: ## \oint_{S}^{ } f(\theta,\phi) \hat \phi \; ds ##Where s is a sphere of radius R.so ds = ##R^2 Sin(\theta) d\theta d\phi ## Where ds is a scalar surface element. If I was working in Cartesian Coordinates I know the unit vector can be pulled out of integral and...

Fx: um2cos(θ)-um3cos(-θ)-um1=Fx [(m2+m3)cos(θ)-m1]u=Fx [m1cos(θ)-m1]u=Fx [cos(θ)-1]m1u=Fx Fy: um2sin(θ)-um3sin(-θ)=Fy

Homework Statement A horizontal water jet produces a wide sheet of parallel-flowing liquid that strikes an inclined plate and then divides, with a fraction of the liquid flowing up the plate and the remainder flowing down the plate. The figure shows a section of the flow. All surfaces of the...
