Question

 Part A

A 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall. The mass is pulled away from the equilibrium position (x = 0) a distance of 17.5 cm and released. It then oscillates in simple harmonic motion with a frequency of 8.38 Hz. At what position, measured from the equilibrium position, is the mass 2.50 seconds after it is released?

–5.23 cm

16.6 cm

–5.41 cm

–8.84 cm

–11.6 cm

 

Part B

A 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall. The mass is pulled away from the equilibrium position (x = 0) a distance of 17.5 cm and released. It then oscillates in simple harmonic motion with a frequency of 8.38 Hz. What is the mass’s maximum speed during this motion?

8.76 m/s

1.47 m/s

9.21 m/s

2.85 m/s

 

Part C

A 23.3-kg mass is attached to one end of a horizontal spring, with the other end of the spring fixed to a wall. The mass is pulled away from the equilibrium position (x = 0) and released. It then oscillates in simple harmonic motion with a frequency of 4.91 Hz. If the mass’s maximum acceleration during the motion is 135 m/s², how far from equilibrium was the mass initially pulled?

90.7 cm

14.2 cm

4.38 m

5.60 m
