Solve the all parts of given problem:
Problem: A 3.08 g bullet moving at 290m/s enters and stops in an initially stationary 3.30 kg wooden block on a horizontal frictionless surface.
Part I: What's the speed of the bullet/ block combination?
Part II: What fraction of the bullet's kinetic energy was lost in this perfectly inelastic collision?
Part III: How much work was done in stopping the bullet?
Part IV: If the bullet penetrated 5.00 cm into the wood, what was the average stopping force?
Please clarify the equations and steps are used to get the answer. Thanks!
