A 0.341-kg block of wood hangs from the ceiling by a string, and a 0.0567-kg wad of putty is thrown straight upward, striking the bottom of the block with a speed of 8.05 m/s. The wad of putty sticks to the block.
(a) Is the mechanical energy of this system conserved?
(b) How high does the putty-block system rise above the original position of the block? |
