Problem 8: In the figure above on the right a 0.001 kg bullet with initial speed v = 1800 m/sec is fired into a 0.5 kg block attached to the end of a 0.60 m rod of mass 0.50 kg. Point A is the pivot point for the rod and the bullet stays inside the block after the collision. What is the angular speed w of the system after the collision? The moment of inertia of the rod about point A is I = Me and the moment of a particle is I = mr?. Treat the block as a particle and also treat the bullet as a particle. Answer: w = 4.5 rad/sec

R Rod Block Bullet Problem 7: The puck in the figure above on the left has a mass of 0.120 kg. The distance of the puck from the center of rotation is originally 0.4 m, and the puck is sliding with a speed of v; = 0.8 m/sec. The string is pulled downward through the hole in the frictionless table and the new distance of the puck from the center of rotation is 0.25 m. What is the new speed of the puck? Answer: vf = 1.28 m/sec Problem 8: In the figure above on the right a 0.001 kg bullet with initial speed vi = 1800 m/sec is fired into a 0.5 kg block attached to the end of a 0.60 m rod of mass 0.50 kg.
