(a) Find the equation of motion if the weight is released from rest 15 inches above equilibrium position x(t) Preview (b) the weight is released 15 inches above the equilibrium position with an upward velocity...
A 24-lb weight, attached to the end of the spring, stretches it 4 inches. Find the equation of motion if the weight is released from rest, from a point 3 inches above the equilibrium.
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.
A block of mass mmm= 3.00 kg is attached to the end of an ideal spring. Due to the weight of the block, the block remains at rest when the spring is stretched a distance hhh= 8.00 cm from its equilibrium length. (Figure 1)The spring has an unknown spring constant k. Take the acceleration due to gravity to be g = 9.81 m/s2m/s2 . Suppose that the block gets bumped and undergoes a small vertical displacement. Find the resulting frequency...
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...
A 3.10 kg fish is attached to the lower end of a vertical spring that has negligible mass and force constant 850 N/m . The spring initially is neither stretched nor compressed. The fish is released from rest. a)What is its speed after it has descended 0.0460 m from its initial position? b)What is the maximum speed of the fish as it descends?
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.
