A force F~ = Fx ˆı + Fy ˆ acts on a particle that undergoes a displacement of ~s = sx ˆı + sy ˆ
where Fx = 6 N, Fy = −3 N, sx = 1 m, and
sy = 2 m.
Find the work done by the force on the
particle.
Answer in units of J

Find the angle between F~ and ~s.
Answer in units of ◦.

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.
