6. One fighter jet makes the same radius turn as another, but at twice the speed. Compared to the slower jet, the centripetal acceleration of the faster jet is Turn Radius

Cross country runners must turn a corner around a tree obstacle, in the rain. a) The first runner takes a wide line to the tree and runs around a curve with a radius of 1.5 m and undergoes a radial acceleration of 10 m/s2. Determine their tangential velocity during the curve. b) The second runner is trying to catch up and so runs closer to the tree. If a loss of control (slip) occurs at a radial acceleration of 22 m/s2, does the runner manage to run around a curve with a radius of 0.50 m at a tangential velocity of 3.5 m/s?

8. We know that acceleration represents a change in velocity. If speed is constant in UCM, what aspect of the velocity is changing as an object experiences centripetal acceleration?
