1. The problem statement, all variables and given/known data Rolling without slipping A) Derive the linear acceleration vector equations for points A, B, C, and O in terms of R, ω, α and θ at this instant. B) R = 0.5 m, ω=-54 r/s and α = 0. Determine the MPH of the vehicle and the vector accelerations of points A, B, C, and O. C) R = 0.5 m, ω=-54 r/s and α = +4.9 rad/sec/sec. Find the magnitude and direction of the acceleration of points O & C. D) R = 0.5 m, ω=-54 r/s and α = +4.9 rad/sec/sec. Determine the magnitude and direction of the acceleration of the vehicle in "g" units and how long it would take to stop. 2. Relevant equations 3. The attempt at a solution A) AA = R α j + Rc (-ω2 R) i AB = 2 R α i + ω2 R j AO = R α i AC = ω2 R j B) V = R ω V = 0.5 x 54 = 27 m/s = 60.4 mph AA = -ω2 R = -1458 i m/s2 AB = - 1458 j AO = 0 AC = 1458 j C) At O AO = R α i ⇒ 0.5 x 4.9 = 2.45 i m/s2 At C AC = 1458 j D) A = R α = 2.45 m/s2 A = 0.25 g t= ω/α t= 11.02 s The above was my attempt. Am I on the right track? Or am I doing this wrong?
