This is the answer for the tension from my solution manual: T2 = m2gsinθ−μm2gcosθ−m2a
So if the cosine cancels out, my question is why does it still appear in the equation?
I still don't understand why the cosine is used because when I draw out all the force vectors the mgcostheta cancels out with the normal force. :/ Unless I am drawing my force diagrams wrong.
Homework Statement
A block of mass m1 = 2 kg and a block of mass m2 = 6 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10 kg. The fixed, wedge-shaped ramp makes an angle of 30 degrees and the coefficient of kinetic...
Hi! Thanks for taking a look at my question and if they were numbers would I combine the 2 equations? A's and B's on one side with C's on the other and get A-2A + B+B = 2C-C (simplified: -A +2B = C)?
Homework Statement
Three vectors are related as by the equations: A+B = 2C and B-2A = -C.
If C= 1i + 2j +3k then what is vector A equal to?
Homework Equations
i, j, and k are unit vectors The Attempt at a Solution
The solution in my answer key says that vector A = vector C but I don't...
