Aparticle moves along a straight line with an acceleration of a 5/(3s13 s2) m/s, where s is in meters. determine the particle's velocity when s -2 m, if it starts from rest when s = 1 m. use simpson's rule to evaluate the integral.

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?
