What is true of a car traveling in a circle of radius r at a constant speed v?O It will have a centripetal acceleration toward the center of the circle of magnitude v2/r.O It will have a centripetal acceleration away from the center of the circle of magnitude v/r.O It will have a tangential acceleration in the direction of the velocity.O It will have a tangential acceleration opposite the direction of the velocity.O It will have non-zero centripetal and tangential accelerations. A car makes a sharp turn. The car enters the turn with speed 8 m/s and leaves the turn with speed 13 m/safter 5 seconds. At one point during the turn, the centripetal acceleration is 1.5 m/s. What is the magnitudeof the total acceleration at this point? Answer in m/s.

Is it possible for an object moving around a circular path to have both centripetal and tangential acceleration? No, because then the path would not be a circle. A (B Yes, this is possible if the speed is constant. No, an object can only have one or the other at any given time. Yes, this is possible if the speed is changing. D
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?
