Answer 1

FHJ is related to GIK

Answer 2

Answer:

A student writes four different expression for the displacement y in a period motion y = a sin"(2 pi r)/(T)y = a sin vty = (a)/(t) sin"(t)/(a)y = (a )/(sqrt(2))[sin'(2 pi r)/(T)+ cos '(2 pi r)/(T)]where a is maximum displacement , x is the speed and T is the time period then dimensionally.
