Physics II HW 1 SHM Name___________________________
- A 100 g object connected to a spring (k= 40 N/m) oscillates on a horizontal frictionless surface with an amplitude of 4.00 cm. Find the period and the total energy of the system.
- What is the period of a pendulum with a length of 2 meters on Earth? On the Moon?
- A 5 kg mass is attached to a spring that is hanging vertically. The spring is stretched 0.25 m from its equilibrium position. What is the spring constant?
- A spring of constant k = 100 N/m hangs at its natural length from a fixed stand. A mass of 3 kg is hung on the end of the spring, and slowly let down until the spring and mass hang at their new equilibrium position.
- Find the value of the quantity x in the figure above.
The spring is now pulled down an additional distance x and released from rest.
- What is the potential energy in the spring at this distance?
- What is the speed of the mass as it passes the equilibrium position?
- How high above the point of release will the mass rise?
- What is the period of oscillation for the mass?
- Calculate the length of a pendulum on earth whose frequency of oscillation is 10 Hz.
- On planet X64J1, the period of a 0.50 m pendulum is 1.8 s. What is the acceleration due to gravity on this planet?
- What is the value of g for a location where a pendulum 1.88 m long has a period of 2.20 s?
- The period of a mass on a spring is 2 s. If k=50 N/m, what is the mass?
- Explain SHM.
- Explain Hook’s law.
