You have two equal masses m1 and m2 and a
spring with a spring constant k. The mass m1 is
connected to the spring and placed on a frictionless horizontal
surface at the relaxed position of the spring. You then hang mass
m2, connected to mass m1 by a
massless cord, over a pulley at the edge of the horizontal surface.

the spring is stretched an amount d1 as shown...

A system consists of a vertical spring with force constant
k = 1,130 N/m, length L = 1.45 m, and object of
mass m = 5.05 kg attached to the end (see figure). The
object is placed at the level of the point of attachment with the
spring unstretched, at position yi =
L, and then it is released so that it swings like a
pendulum.

A linear spring-mass system (without friction) satisfies m(d^2x/dt^2) = -kx, Derive that m/2 (dx/dt)^2 + k/2 x^2 = constant = E. Consider the initial value problem such that at t = 0, = x_0 and dx/dt = v_0. Evaluate E. Using the expression for conservation of energy, evaluate the maximum displacement of the mass from its equilibrium position. Compare this to the result obtained from the exact explicit solution.

A linear spring-mass system (without friction) satisfies m(d^2x/dt^2) = -kx, Derive that m/2 (dx/dt)^2 + k/2 x^2 = constant = E. Consider the initial value problem such that at t = 0, = x_0 and dx/dt = v_0. Evaluate E. Using the expression for conservation of energy, evaluate the maximum displacement of the mass from its equilibrium position. Compare this to the result obtained from the exact explicit solution.
