Amachine part is undergoing shm with a frequency of 5.00hz and amplitude 1.80cm . how long does it take the part to gofrom x=0 to x= -1.80 cm
well i know that x=acos(ωt)
and
ω=2πf so we have -1.8cm= 1.8cm * cos(2πft)
we end up with -1=cos(2Ď€ft) i know that cos(Ď€)=-1so ft =1/2 but if that is true
then i have 5s^-1*t= 1/2 gives t= .1s
not .05s like the book says can anyone me with the problem i'mhaving.

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.
