Answer question 2 Multiple Choice Questions (9 pts)1. A student is given a block and a spring. He is told that the block has a mass of 0.500 kg andthat the spring constant is 60.0 N/m. He calculates the theoretical period of oscillation will be0.574 s. He then attaches the block to the spring and times the period using 20 oscillations. Hediscovers that the actual period of oscillation is 0.450 s. Which of the following statements bestexplains the discrepancy between the theoretical and the actual period of oscillation?A) Air resistance was ignored in the theoretical calculation.B) The spring's mass was ignored in the theoretical calculation.C) The spring constant was less than 60.0 N/m.D) The block's mass was less than 0.500 kg.2. A mass is oscillating up and down on a spring. Position A is the lowest point, C is the highestpoint and B is exactly in the middle of A and C. Describe the changes in the various types ofenergy as the mass moves from position B to position C.Spring Potential EnergyGravitational Potential EnergyKinetic energyA)decreasingincreasingdecreasingB)he EardC)decreasingdecreasingincreasingdecreasingdecreasingdecreasingD)increasingincreasingincreasing3. A student measures the maximum speed of a mass oscillating back and forth on a spring. Onthe first oscillation she finds the maximum speed to be 0.855 m/s. A few oscillations later shefinds the maximum speed to be 0.628 m/s. What is the best explanation of this? bA) The mass transferred energy to the spring increasing the maximum spring potential energy.B) The spring transferred energy to the mass decreasing the maximum spring potential energy.C) The mass-spring system lost energy to the surroundings.D) As energy was transferred back and forth between the spring and the mass, on average agreater share of the energy was being transferred to the spring.

We do not need the analogy in Equation 16.30 to write expressions for the translational displacement of a pendulum bob along the circular arc s(t), translational speed v(t), and translational acceleration a(t). Show that they are given by s(t) = smax cos (smpt + ) v(t) = vmax sin (smpt + ) a(t) = amax cos(smpt + ) respectively, where smax = max with being the length of the pendulum, vmax = smax smp, and amax = smax smp2.

You are working in an observatory, taking data on electromagnetic radiation from neutron stars. You happen to be analyzing results from the neutron star in Example 11.6, verifying that the period of the 10.0-km-radius neutron star is indeed 2.6 s. You go through weeks of data showing the same period. Suddenly, as you analyze the most recent data, you notice that the period has decreased to 2.3 s and remained at that level since that time. You ask your supervisor about this, who becomes excited and says that the neutron star must have undergone a glitch, which is a sudden shrinking of the radius of the star, resulting in a higher angular speed. As she runs to her computer to start writing a paper on the glitch, she calls back to you to calculate the new radius of the planet, assuming it has remained spherical. She is also talking about vortices and a superfluid core, but you dont understand those words.
