1. A 0.25 kg harmonic oscillator has a total mechanical energyof 4.1J. If the oscillation amplitude is 20.0cm. what is theoscillation frequency?
2. A 0.250-kg stone is attached to an ideal spring and undergoessimple harmonic oscillations with a period of 0.640 s. What is theforce constant (spring constant) of the spring?
3. An object of mass m = 8.0 kg is attached to an ideal springand allowed to hang in the earth's gravitational field. The springstretches 2.2cm before it reaches its equilibrium position. If itwere now allowed to oscillate by this spring, what would be itsfrequency?
4. A 0.39-kg block on a horizontal frictionless surface isattached to an ideal spring whose force constant (spring constant)is 570N/m. The block is pulled from its equilibrium position at x =0.000 m to a displacement x = +0.080 m and is released from rest.The block then executes simple harmonic motion along the horizontalx-axis. When the position of the block is 0.057m, its kineticenergy is closest to?
