A block attached to the lower end of a vertical spring oscillates up and down. If the spring obeys Hooke’s law, the period of oscillation depends on which of the following?

I. Mass of the block

II. Amplitude of the oscillation

III. Force constant of the spring

• I only

• II only

• I and II

• I and III

Harper, Mia, and Charlotte are working on a physics interactive together. They come across an interesting experiment where a 2.0 kg block is attached to a spring. OK. Not really that interesting. But anyway, they still have to calculate the spring constant because it's part of the lab. Given that the block accelerates at 13 m/s² when it is 0.75 m away from the equilibrium position. Can you help them figure it out K?

• 35 N/m

• 0.12 N/m

• 4.8 N/m

• 9.8 N/m

A student attaches a block to a vertical spring so that the block-spring system will oscillate if the block-spring system is released from rest at a vertical position that is not the system’s equilibrium position. The system oscillates near Earth’s surface. The system is then taken to the Moon’s surface, where the gravitational field strength is nearly 1/6 that of the gravitational field strength near Earth's surface. Which of the following claims is correct about the period of oscillation for the system?

• The system has a longer period on Earth than on the Moon.

• The system has a shorter period on Earth than on the Moon.

• The system has the same period on Earth as the Moon.

• The period of oscillation cannot be determined without knowledge of the spring constant, the mass of the block, and the exact gravitational field strength near Earth’s surface and the Moon’s surface.
