Best ResponseYou've already chosen the best response.0dw:1360767373040:dw Linear velocity before = wr = 25*0.07 = 1.75 let it remain in contact with plane for time dt, then, (Nsinx)dt = m(1.75) also, it stops rolling, then Tdt = I(25) where T=torque => (Ncosx)(0.07) dt= (1/2)m(0.07)^2 * 25 Divide both eqns

Best ResponseYou've already chosen the best response.0I do not understand the question. You cannot bring the cylinder immediately to rest. That would mean you make a finite amount of energy disappear in an infinitesimal amount of time. You would need for that an infinite power, which is not physically acceptable.
