Problems 1 and 2 A mass weighing 3/4 slug, attached to the end of a spring whose constant 72 lb/ft. Initially the mass is released from rest from a point 3 inches above the equilibrium position. Find the equation of motion. Determine the equation of motion if the mass in problem 1 is Initially released from the equilibrium position with a downword velocity of 2ft/sec. Initially released from a point 6 inches below equilibrium with an upward velocity 2ft/sec.
a 4.00 lb weight stretches a certain spring 0.500 ft. With this weight attached, the spring is pulled 3.00 inches longer than its equilibrium length and released. Find the equation of the resulting motion, assuming no damping. y=?
1. A mass weighing 8 pounds is attached to a 4 foot long spring and stretches it to 8 feet long. The medium offers a damping force equal to 0.5 times the instantaneous velocity. Find the equation of motion if the mass is released from rest at a position 18 inches above the equilibrium. 1. A mass weighing 8 pounds is attached to a 4 foot long spring and stretches it to 8 feet long. The medium offers a damping...
A 128 lb weight is attached to a spring that has a spring constant of 64 lb/ft. The system is started into motion by displacing it 6 in above the equilibrium position and by simultaneously applying an external force of f(t) = 8 sin 4t. There are no damping forces. Find the equation of motion for these conditions. Find the period and frequency of the motion. Draw a graph of the solution.
A mass weighing 32 pounds is attached to the lower end of a coil spring. It stretches the spring by 1 foot and comes to rest at equilibrium position. At time t = 0, the mass is pulled downward 1 foot, and released. Suppose the damping is equivalent to 8x' pounds and no external forces are present. Find the displacement of the mass at time t, and write your final answer in phase-amplitude form.
