A golf ball is struck an initial velocity of 65.0m/s at an angle 12.0° above the horizontal. It lands at the same height from which it was struck. A) find the range of the gold ball

B) find the maximum altitude reached by He golf ball.

C) how long does it take to reach the maximum height?

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?
