A 1.25-kg wooden block rests on a table over a large hole shown. A
5.00-9 bullet with an initial velocity
v is fired upward into the bottom of
the block and remains in the block
after the collision. The block and
bullet rise to a maximum height of
22.0 cm. Calculate the initial
velocity of the bullet. [in m/s]. use
the correct number of significant
figures based on the data provided.​

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
