Question

A 115-kg sculpture hangs from a horizontal rod that serves as a pivot about which the sculpture can
oscillate. The sculpture's moment of inertia with respect to the pivot is 10.4 kg- m², and when it is swung at
small amplitudes, it is found to oscillate at a frequency of 0.346 Hz. How far is the pivot from the
sculpture's center of mass?
Number

A simple pendulum comprised of a bob of mass m = 172 g and a lightweight string of length 76.0 cm is released from rest from an initial angle of 28.0° from the vertical. (a) Using the approach of simple harmonic motion, what is the maximum speed of the pendulum bob? m/s(b) Using the approach of simple harmonic motion, what is the maximum angular acceleration of the bob? rad/s2(c) How does the speed found in part (a) compare with that found by using a conservation of energy approach? (Assume that the values are nearly the same if within 10% of each other.) The speed is very different from that from part (a). The speed is nearly the same as that from part (a).

A 1000 kg car carrying four 80 kg persons is traveling over “washboard" speed bumps spaced at regular intervals. The bumps are located 4 m apart. The car is observed to bounce with maximum amplitude when its speed is 16 km/h. The car now stops and the four people get out. By how much does the car body rise on its suspension owing to the decrease in weight?
