The stated answer is 5 m/s up the incline. By the way the acceleration we get from using T= 50 N results in acceleration of the block down the plane.

I'm not sure I'm following you exactly. What would you say the acceleration of the block is? 50N/20kg = 2.5 m/s? If so, that's not the stated answer. Of course the stated answer could be wrong. That is the answer i got btw the first time I tried this, but I don't think it's right to assume...

If we let that be the case, then the tension in the rope is balancing out the gravitational force along the ramp, which means that there is no acceleration. From the solution given, I can tell you that there is a nonzero acceleration. Have I missed something in your analysis? Thank you for...

You just made a couple mistakes with your sign: You have 4.9t²-10t-2.3=0 which is correct but when you use the quadratic formula you have (it's not the Pythagorean btw) -10 ± √((-10²)-4(4.9)(-2.3))/ 2(4.9) but it should be (10 +/- sqrt[(-10)^2 - 4(4.9)(-2.3)])/(2(4.9)) which is...

Homework Statement The included image shows the problem in its entirety. The problem is from a physics review book that I have which also includes the answer, but the explanation is beyond me. I was hoping someone could walk me through the solution. T, the rope tension (constant...
