Your two kitties, Fuzz Aldrin and Ramses are perched up 2.5 m above the ground when they get startled and jump off at the same speed of 2.5 m/s. Fuzz Aldrin jumps at an angle of 45⁰ above the horizontal and Ramses jumps at an angle of 45⁰ below the horizontal. (A) Calculate how much longer Fuzz Aldrin is in the air compared to Ramses.

(B) Calculate the speeds the kitties have when they strike the ground.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
