A block-spring system consists of a spring with constant k = 445 N/m attached to a 2.25 kg block on a frictionless surface. The block is pulled 4.10 cm from equilibrium and released from rest. For the resulting oscillation, find the amplitude, angular frequency, frequency, and period. What is the maximum value of the block's velocity and acceleration?

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....

In a class question you solved the problem of the "Ballistic Pendulum". This problem might be called a "Ballistic Spring". A spring of equilibrium (un-stretched) length L 0 is hung vertically from one end. A mass M is attached to the other end of the spring and lowered so that the mass hangs stationary with the spring stretched a distance Δ L. The position of the bottom end of the un-stretched spring is defined as y = 0 and shown...
