A certain spring has a spring constant k1 = 420 N/m as the spring is stretched from x = 0 to x1 = 34 cm. The spring constant then changes to k2 = 330 N/m as the spring is stretched to x2 = 79 cm. From x2 = 79 cm to x3 = 97 cm the spring force is constant at F3 = 120 N. (a) Use the area under the curve to calculate the work, in joules, necessary to...

A massless spring of spring constant k = 4872 N/m is connected to a mass m = 210 kg at rest on a horizontal, frictionless surface. Part (a) The mass is displaced from equilibrium by A = 0.73 m along the spring’s axis. How much potential energy, in joules, is stored in the spring as a result? Part (b) When the mass is released from rest at the displacement A= 0.73 m, how much time, in seconds, is required for...

A spring with spring constant 32 N/m is attached to the ceiling, and a 4.7-cm-diameter, 1.2 kg metal cylinder is attached to its lower end. The cylinder is held so that the spring is neither stretched nor compressed, then a tank of water is placed underneath with the surface of the water just touching the bottom of the cylinder. When released, the cylinder will oscillate a few times but, damped by the water, quickly reach an equilibrium position. When in...
