D Question 1 1 pts An object is undergoing simple harmonic motion. It has a maximum displacement of 1 m. It takes a time of 1 second to go from a displacement of 1 m to a displacement of -1 m. What is its time period? 3.1 seconds 2.0 seconds O 0.5 seconds 1.0 seconds D Question 2 1 pts An object is undergoing simple harmonic motion. If the total mechanical energy at maximum displacement from equilibrium is 1.0 joule, what is the kinetic energy at zero displacement from equilibrium? O 3.1 joule 0.5 joule O zero 1.0 joule

Explanation / Answer

1) The time for one complete oscillation is called the period (T)

   Here one oscillation will be from +1 to -1 and then -1 to +1.

So Period = 1 + 1 = 2 seconds

2) Total mechanical energy = 1.0 J

At zero displacement from equilibrium, potential energy = 0

So kinetic energy = 1.0 J
