    A spring (k= 12 N/m), which can be stretched or compressed, lies flat on a frictionless table. One end of the spring is attached to the wall, and the other has a 3.3 kg mass attached. Assume the equilibrium position is labelled zero. A student pulls the mass out to x=14.0cm and releases it from rest at time t=0. The mass oscillates as a SHM. What is the speed of the mass at time t=14.4 s? Answer: Check

    A mass of 500 gm is attached to a spring (k = 24.5 N/m) on a horizontal, frictionless surface. A force of 4.90 N pulls the mass to the right, displacing it some distance, x, from its equilibrium position. The mass is then released and oscillates in simple harmonic motion. (A) What is the maximum speed of the mass for this motion? ANSWER: 1.4 m/s (B) What is the position, x, of the mass 0.500 seconds (this is time, t)...
