Ben Rushin is waiting at a stoplight. When it finally turns green, Ben accelerated from rest at a rate of a 6 m/s^2 for a time of 4.10 seconds. Determine the displacement of Ben's car during this time period. What variable is being described by "from rest"?
A. Acceleration
B. Displacement
C. Final velocity
D. initial Velocity
E. Time

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.
