  2. 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.

  4. 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.

  5. 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 amplitude of the oscillations.

  6. 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 period of oscillations.

  7. 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.
