A rifle bullet with a mass m = 9.00 g strikes and embeds into a wooden block with a mass M = 1.00 kg that rests on a frictionless, horizontal surface and is attached to a spring. After the collision the spring compresses by a distance of 18.0 cm. Assuming the spring obeys Hook’s Law and has a spring constant k = 300 N/m: a. Find the velocity of the bullet-block system after the collision. b. Find the velocity of the bullet before the collision. c. Find the energy loss due to the collision. d. Find the period of oscillations.
