A 0.005 kg bullet traveling horizontally with speed 1.00 x 103 m/s strikes an 18.0-kg door, embedding itself 10.0 cm from the side opposite the hinges. The 1.00 m wide door is free to swing on its frictionless hinges.

A) What is the bullet’s initial angular momentum relative to the door’s axis of rotation?

B)At what angular speed does the door swing open immediately after the collision?

A 10.0 kg uniform, a disk-shaped wooden door (radius 0.500 m) hangs vertically and can rotate freely about an axis that passes through its rim. A 0.020-kg bullet shot horizontally with a speed of 375 m/s, hits, and embeds itself in the door at a point diametrically opposed to the pivot point of the door. What is the angular speed of the door after the collision? (You can neglect the mass of the bullet after the collision.) After the collision,...

A 10.0-g bullet is fired into, and embeds itself in, a 1.85-kg block attached to a spring with a force constant of 22.4 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block. (No Response)...
