Unformatted text preview: 77777 777 . 20. 21. 22. 23. 24. 25. 26. 27. A 20 g bullet moving at 1000 m/s is ﬁred through a 0.50 kg block of wood emerging at a speed of 400 m/s. What is the kinetic energy of the block that results from the collision if the block had not been moving prior to the collision and was free to move?
