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(2Ï€ft) i know that cos(Ï€)=-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.
