1. The problem statement, all variables and given/known data A 10 kg mass is on a frictionless inclined plane 30 degrees to the horizontal. At the top of the plane is a pulley that has a rope attached to mass with tension T = 75 N. If the mass starts from rest, what is its velocity after 2 seconds? 2. Relevant equations F = ma Vf=Vi + at 3. The attempt at a solution So my book lists the formula as T = mgsinθ + ma. I set the problem up pretty much the same as: ∑Fx = max 75 N - 10 N = (10 kg) a My acceleration is 6.5 m/s2. Plugging this value in to vf=vi + at, I get 13.0 m/s but my book says it's supposed to be 5 m/s. What am I doing wrong? Thanks in advance!
