1. –/2 points Notes Question: Walker4 13.P.050. A 0.40 kg mass is attached to a spring with a force constant of  33  N/m and released from rest a distance of  5.3  cm from the equilibrium  position of the spring. (a) Give a strategy that allows you to find the speed of the mass when it is halfway to the equilibrium position.    (b) Use your strategy to find this speed.   m/s 2. –/1 points Notes Question: Walker4 13.P.061. A large pendulum with a 200-lb gold-plated bob 12 inches in diameter is on display in the lobby of the United Nations building. It is used to  show the rotation of the Earth -- for this reason it is referred to as a Foucault pendulum. If the pendulum is  15.2  m in length, what is the  least amount of time it takes for the bob to swing from a position of maximum displacement to the equilibrium position of the pendulum?  (Assume that the acceleration due to gravity is  g  = 9.81 m/s 2  at the UN building.)    s 3. –/2 points Notes Question: Walker4 13.P.069. Suspended from the ceiling of an elevator is a pendulum of length  L . (a) What is the period of this pendulum if the elevator accelerates upward with an acceleration  a ? Give your answer in terms of  L g , and  a . T
