" A mass hanging from a vertical spring is somewhat more complicated than a mass attached to a horizontal spring because the gravitational force acts along the direction of motion. Therefore, the restoring force of the oscillations is not provided by the spring force alone, but by the net force resulting from both the spring force and the gravitational force. Ultimately, however, the physical quantities of motion...

A mass weighing 4 pounds is attached to a spring whase constant is 2 b/ft. The medium offers a damping force that is numerically equal to the instantaneous velocity. The mass is initially released from a point 1 foot above the equilbrium position with a downward velocity of 10 ft/s. Determine the time at which the mass passes through the equilibrium position. (Use g 32 ft/s2 for the acceleration due to gravity.) Find the time after the mass passes through...

One end of a spring with a force constant of k 10.0 N/m is attached to the end of a long horizontal frictionless track and the other end is attached to a mass m = 2.20 kg which glides along the track. After you establish the equilibrium position of the mass-spring system, you move the mass in the negative direction (to the left), compressing the spring 1.73 m. You then release the mass from rest and start your stopwatch, that...

6. A spring-mass system is oscillating under no external force, with a damping constant equal to 2 and spring constant equal to 1. If at t = 0 we release (x'(0) = 0) the mass from a stretched position at a displacement of x(0) = 3. Write down the modelling ODE and solve it to find the solution. What will happen eventually to the system? Is it overdamped or undedamped? Will it oscillate?
Engineers have invented a new kind of spring whose restoring force is proportional to the third power of displacement
Engineers have invented a new kind of spring whose restoring force is proportional to the third power of displacement: |F(x)| = |βx3| where B = (1/9) N/m3. One end of this spring is fixed to the bottom of an inclined plane which makes an angle θ = 36.87° with respect to the horizontal, and the other end is stretched up the incline and attached to a block of mass m = 3.00 kg. The spring is initially stretched a distance...
