1. The problem statement, all variables and given/known data Hey all! I'm new here but I think I'll like it. :) I have a question that I can't seem to figure out. Here is the question in short: GIVEN: A wheel of radius 1m on a vertical plane rotates with an angular acceleration of 4rad/sec2. The wheel starts from rest (ωo = 0). Point P, on the wheel, is at 57.3° from the horizontal. REQUIRED: At t=2sec, (a) what is the angular acceleration of the wheel? (b) What is the tangential speed and the total acceleration at P? and (c) What is the angular position of P? 2. Relevant equations Some equations needed might be: ωf=αt + ωo v=ωr θ=s/r 3. The attempt at a solution I have attempted all of them. For (a) my answer is to use the first formula I wrote to find 8rad/sec. For (b) I am confused because I don't know if the rotation is Clockwise or Counter Clockwise. Since the rotation is vertical, gravity must have some role in it. Does gravity help the rotation at P or is it against it? (c) I think this one is easy. Solve for s in the third formula. 57.3 radians is my answer. Please help me out. Thanks so much!
