Car A is traveling on a highway at a constant speed 0( ) 60mi/h, Av = and is 380 ft from the entrance of an access ramp when car B enters the acceleration lane at that point at a speed 0( ) 15mi/h, Bv = Car B accelerates uniformly and enters the main traffic lane after traveling 200 ft in 5 s. It then continues to accelerate at the same rate until it reaches a speed of 60mi/h, which it then maintains. Determine the final distance between the two cars.

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.
