Question

A book with many printing errors contains four different formulas for the displacement y of a particle undergoing a certain periodic motion :
(a) y = a sin 2πt / T
(b) y = a sin vt
(c) y = (a/T) sin T/a
(d) y = (a√2) (sin 2πt / T + cos 2πt / T)
{a = maximum displacement of the particle, v = speed of the particle, T = time-period of motion). Rule out the wrong formulas on dimensional grounds.

Answer 1

Answer:

I think answer is (a), y= A Sinwt

=A Sin2pi*t/T
