A spring lies on a horizontal table, and the left end of the spring is attached to a wall. The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.75 kg, and the spring has a spring constant of 77 N/m. The coefficient of static friction between the box and the table on which it rests is us = 0.59. How far can the spring be stretched from its unstrained position without the box moving when it is released?
A mass of 0.75 kg is suspended from a spring. If 1.41 J of work is done against the spring as the mass is pulled 0.15 m away from its equilibrium position, what is the spring constant of the spring?
A marble with a mass of 0.085 kg compresses a spring 5.1 cm. If the spring has a constant k = 150 N/m, what will the velocity of the marble be when it's released?
A chair, having a mass of 5.5 kg, is attached to one end of a N spring with spring constant 90. The other end of the spring m is fastened to a wall.
