Question

A simple harmonic oscillator consists of a mass m attached to a spring with spring constant k, with displacement given by
x = A sin(wt + ¢) . Which one of the following is NOT true?
O The frequency is independent of the amplitude
O The potential energy is a maximum when (wt + 4) = 0
The kinetic energy is a maximum when (wt + ¢) = 0
O The restoring force must be proportional to the negative of the displacement
O Increasing the mass will decrease the frequency

A spring hangs vertically from a ceiling. The spring constant of the spring is k=15 N/m. A 2kg object has been attached to the spring and the spring has already come to its new equilibrium. Someone pulls the object down by 5cm and releases it at time t = 0s. The spring and object begin to oscillate under simple harmonic motion. Find the total energy of the system, the maximum kinetic energy, the maximum potential energy, and the positions where the maximum energies occur. Answers: 0.01875 J, 0.01875 J
The length of a simple pendulum is 0.85 m and the mass of the particle (the “bob”) at the end of the cable is 0.32 kg. The pendulum is pulled away from its equilibrium position by an angle of 7.5° and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. Using the position of the bob at its lowest point as the reference level, determine the total mechanical energy of the pendulum as it swings back and forth.
A cart of mass 0.72 kg is attached to one end of of a spring and placed on a low-friction track, inclined at an angle of 56.0 degrees with respect to the horizontal. The cart is found to be in equilibrium when the spring is stretched to a total length of 44.8 cm. Given that the rest length for the spring is 12.8 cm, what is the spring constant for the spring?
