A mass m = 1 1 kg is attached to a spring with constant k = 4 N/m and a dashpot with variable damping coefficient c. If the mass is to be pulled 7 m beyond its equilibrium (stretching the spring) and released with zero velocity, what value of c ensures that the mass will pass through the equilibrium position and compress the spring exactly 1 m before reversing direction?

A mass m = 1 kg is attached to a spring with constant k = 9 N/m and a dashpot with variable damping coefficient c. If the mass is to be pulled 8 m beyond its equilibrium (stretching the spring) and released with zero velocity, what value of c ensures that the mass will pass through the equilibrium position and compress the spring exactly 1 m before reversing direction?
6) A mass-spring system consists of a 250-g mass hanging from a spring with a spring constant of k 0.18 J/m2. The mass is pulled down 7.1 cm from its equilibrium position and released from re a) How much work did the person do when she pulled the spring down from its equilibrium position? Assume that the mass was at rest before she pulled it down, and before it was released. (Use the energy-interaction model, not the expression W FavgAx,...
A 2.60 kg mass is pushed against a horizontal spring of force constant 25.0 N/cm on a frictionless air table. The spring is attached to the tabletop, and the mass is not attached to the spring in any way. When the spring has been compressed enough to store 12.5 J of potential energy in it, the mass is suddenly released from rest. Part A Find the greatest speed the mass reaches. Part C What is the greatest acceleration of the...

A spring is compressed 15 cm from its natural length. If it requires 100 N of force to compress the spring this distance, what is the spring constant of the spring? how much energy is stored in the spring? what will the angular frequency of the spring be if it is attached to a 100 g mass and released to oscillate?
A block of mass m = 6.14 kg is attached to a spring with spring constant k = 1682 N/m and rests on a frictionless surface. The block is pulled, stretching the spring a distance of 0.135 m, and is held still. The block is then released and moves in simple harmonic motion about the equilibrium position. (Assume that the block is stretched in the positive direction.) (b) Where is the block located 3.24 s after it is released? (Give...
A 0.90 kg mass is attached to a light spring with a force constant of 24.9 N/m and set into oscillation on a horizontal frictionless surface.

An ideal spring hangs from the ceiling. A 1.45 kg mass is hung from the spring, stretching the spring a distance d 0.0845 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L-0.0295 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position? kinetic energy Equilibrium position
