A block of mass m = 1.3 kg is vibrating on a spring with
a force constant of k = 194 N/m. When the
instantaneous speed of the block is v = 0.55 m/s, the
block is 0.30 m away from equilibrium. Find the
maximum speed of the block during the vibrations.

A block of mass m = 0.75 kg is connected to a spring. The
block is in simple harmonic motion during which its maximum
velocity is vmax = 1.2 m/s and its maximum acceleration is amax
= 0.36 m/s2. Find the total energy of the system.

A block of mass m = 0.75 kg is connected to a spring. The
block is in simple harmonic motion during which its maximum
velocity is vmax = 1.2 m/s and its maximum acceleration is amax
= 0.36 m/s2. How far is the block from equilibrium at the
moment when its kinetic energy is equal to its potential
energy? Assume that potential energy is zero at equilibrium.
