WEBSo, our equation of motion is: F c = m a c, F N + m g = m v 2 r. To find the critical speed, we set the normal force to zero, as we did with the tension before, and we arrive at the same equation for the critical speed: 0 + m g = m v c 2 r, v c = g r. So the critical speed of the passenger is v c = m s 2 ⋅ 15 m = 12 m s.
