1. The problem statement, all variables and given/known data http://img688.imageshack.us/img688/5277/loopb.jpg [Broken] A cylindrical shell is released from rest and rolls down an incline without slipping. Find speed of shell at the top of the loop. h(incline) = 2.0m h(loop) = 1.3m 3. The attempt at a solution vf = sqrt(g * yi) vf = sqrt(9.8m/s^2 * 2.0m) vf = 4.42719m/s = vi(loop) KEi = PEf + KEf 1/2mvi^2 = mgy + 1/2mvf^2 + 1/2mr^2(v^2/r^2) 1/2vi^2 = gy + 1/2vf^2 + 1/2vf^2 1/2(4.42719m/s)^2 = -9.8m/s^2(1.3m) + 1/2vf^2 + 1/2vf^2 vf = 1.71464m/s Would this be correct?
