for the simple harmonic motion described by d=4cos(8t) find the following
a) max displacement
b) frequency
c) period
d) the least positive value t for which d = 0
for the simple harmonic motion described by d=4cos(8t) find the following
a) max displacement
b) frequency
c) period
d) the least positive value t for which d = 0
a) max displacement
b) frequency
c) period
d) the least positive value t for which d = 0
Solution
giiven d=4cos(8t)
comparing with y=acos(bx+c)
a) max displacement =a=4
b) frequency=b/(2)=(8)/(2) =4
c) period =2/b=2/(8)=1/4
d) the least positive value t for which d = 0
4cos(8t)=0
cos(8t)=0
(8t)=/2
t=/(2*8)
t=1/16
