The graph shows the displacement xx (in cm) versus time tt (in seconds) for a particle undergoing simple harmonic motion. (1 pt) Determine the amplitude of the oscillation in  meters. (1 pt) Determine the time period of the oscillation in seconds. (2 pts) If the object undergoing simple harmonic motion has a mass of 0.6kg, determine the elastic constant. (2 pts) What is the total energy of the oscillator.

An ideal gas is kept at a constant pressure of 50 kPa. A total of 800 J of heat is added to the gas, and its internal energy increases by 500 J. (3 pts) Using the First Law of Thermodynamics, calculate the work done by the gas during this process. (3 pts) Calculate the change in volume of the gas during this process.

A cooling fan is turned off when it is running at 850 rpm. It turns 1250 revolutions before it comes to rest. (3 pts) What was the fan’s angular acceleration in rad/s2, assuming it is constant. (3pts) How long did it take the fan to come to a complete stop?

A figure skater can increase her spin rotation rate from an initial rate of 0.66 rev/s to a final rate of 2.5 rev/s. If her initial moment of inertia was 4.6kgm2, what is her final moment of inertia? How does she physically accomplish this change?
