SHMHard

Question

If a SHM is given by y = (sin ωt + cos ωt) m, which of the following statements are true?

Options

A.The amplitude is 1m   
B.The amplitude is (√2) m
C.Time is considered from y = 1 m
D.Time is considered from y = 0 m

Solution

Given  y = (sin ωt + cos ωt)        y = √2 sin (ωt + π/4)
So A = √2 m and at      t = 0    y = 1m
