A bullet of mass 0.014 kg and initial speed 440 m/s penetrates an initially stationary wooden block with a of mass 0.44 kg and lodges in it. How much mechanical energy was lost during the collision? (This mechanical energy was transformed into sound and friction generated heat.)
1) A 3.00 g bullet traveling horizontally at 400 m/s hits a 3.00 kg wooden block which is initially at rest on a smooth horizontal table. The bullet buries itself in the block without passing through. The speed of the block after the collision is a) 0.4 m/s. b) 1.2 m/s. c) 2.0 m/s. d) 2.8 m/s. e) 3.6 m/s. 2) What type of collision was seen in the previous problem? a) elastic collision b) inelastic collision c) perfectly elastic...
