Unformatted text preview: radius R = 0.500 m). (a) Is mechanical energy conserved when it is moving on the track? What is the value of the mechanical energy of the ball? (b) What is Δx so that the ball can reach a speed of 0.350 m/s after it leaves the end of spring? (c) What is the centripetal acceleration of the ball when it begins to move on the circular track (Position A)? Solution: (a) Yes, mechanical energy is conserved: 1 1 Eel = Ek = mv 2 = (1kg )(3.5m / s )2 = 6.125J = 6.13J 2 2...
