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 |
