Calculus-based Physics 1: (it6100)

A miniature, spring-loaded, radio-controlled gun is mounted on an air puck. The gun's bullet has a mass of 4.00 g, and the gun and puck have a combined mass of 105 g. With the system initially at rest, the radio-controlled trigger releases the bullet, causing the puck and empty gun to move with a speed of 0.400 m/s. Of the total kinetic energy of the gun-puck-bullet system, what percentage is in the bullet?

A 5.00-g bullet is fired into a 580-g block of wood suspended as a ballistic pendulum. The combined mass swings up to a height of 10 cm. What was the magnitude of the momentum of the combined mass immediately after the collision?
