A particle with mass 1.09 kg oscillates horizontally at the end of a horizontal spring. A student measures an amplitude of 0.963 m and a duration of 125 s for 8.0×10^1cycles of oscillation. Find the frequency, ? the speed at the equilibrium position, ?max, the spring constant, ?,   the potential energy at an endpoint, ?max, the potential energy when the particle is located 62.3% of the amplitude away from the equiliibrium position, ?, and the kinetic energy, ?, and the speed, ?, at the same position.   I have found the frequency(0.640), Vmax(3.87) and the spring constant(17.61). Its the second half that I need help with. I bolded the information in the 2nd half that I need help with. Thank you.

In the physics Lab, you measure a max speed of the pendulum of 0.55m/s. If the maximum deflection angle is 8 degrees, what is the pendulum's length?

A 190 g mass suspended from a spring oscillates in simple harmonic motion. The mass completes 2 cycles every second. Calculate the spring constant.

A pendulum that consists of two uniform rings, the first ring has Radius R = 12 cm and mass 2.5kg,  and the second ring has radius r= 7cm and mass 1.6kg. Both rings are attached to a rod of mass 0.15kg. The pendulum swings freely about frictionless pivot o. If the pendulum is to have a period of 2.2 a for small oscillations, what must be the rod length L?

A pendulum is formed by placing a horizontal axis at various positions of a measuring stick of length 108 cm. What is the period in seconds of the pendulum when the axis is placed at the 81.0-cm mark?

If a 0.350-kg mass is attached to a vertical spring and lowered slowly, the spring stretches 12.0 cm. The package is now displaced from its equilibrium position and undergoes simple harmonic oscillations when released. What is the period of the oscillations? g = 9.80 m/s
