A 7.05 bullet traveling at 520 m/s embeds itself in a 1.85kg wooden block at rest on a frictionless surface. The block is attatched to a spring with l= 85.0 N/m.
1. Find the period.
2. Find the amplitude of the subsequent simple harmonic motion.
3. Find the total energy of the bullet+block+spring system before the bullet. Express answer with appropriate units.
