Q. The velocity of waves on a string is 96 m/s. If the frequency of standing waves is 474 Hz, how far apart are two adjacent nodes?

Q. An 8.00 g bullet is fired at a speed of 216 m/s into a 190 g block that is initially at rest at the edge of a table of 1.00 m height. The bullet fully embeds itself in the block before the bullet-block system launches off the table. How far in the x-direction will the block-bullet system travel before striking the ground?
