Unformatted text preview: etal acceleration of the ball when it is about to leave the circular track (Position C)? (c) What is Δx , the maximum amount the ball compresses the spring? Solution: (a) Yes, mechanical energy is conserved: E = E p = mgh = (1kg )(9.8 N / m2 )(0.625m) = 6.125J = 6.13J (b) Mechanical energy is conserved here: 1 E p = Ek , mgh = mv 2 2 Centripetal acceleration is: a = v 2 / R Then a = 2 gh / R = 2(9.8m / s 2 )(0.625m) / (0.5m) = 24.5m / s 2 (c) Mechan...
