A bullet of mass m is fired into a block of mass M that is at rest. The block, with the bullet embedded, slides distance d across a horizontal surface. The coefficient of kinetic friction is k. Part A Find an expression for the bullet's speed bullet. Express your answer in terms of the variables m, M, k, d, and appropriate constants. View Available Hint(s) M+m Vbullet = 2k.gd m Submit Previous Answers Part B Correct What is the speed of a 10 g bullet that, when fired into a 11 kg stationary wood block, causes the block to slide 4.6 cm across a wood table? Assume that k = 0.20. Express your answer with the appropriate units.
