An object undergoing simple harmonic motion has amplitude of 2.3 m. if the maximum velocity of the object is 15 m/s, what is the object's angular frequency?

Angular frequency,

Explanation:

Given that,

Amplitude of simple harmonic motion, A = 2.3 m

Maximum velocity of the object,

To find,

The object's angular frequency.

Solution,

The equation of the displacement of particle is given by :

On differentiating above equation, we get the expression for maximum velocity as :

So, the angular frequency of the object is 6.52 rad/s.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
