The displacement

y

of a particle is given by

y = 4\,\,{\cos ^{ 2}}\left( {\frac{t}{2}} \right)\,\,\sin \left( {1000t} \right)

. This expression may be considered to be a result of the superposition of how many simple harmonic motions?

View answer and explanation

Correct option: B

3

Option B (3) is correct because the given expression can be rewritten as a superposition of three simple harmonic motions using trigonometric identities.
