The equation of a travelling wave is

y=15 \sin ^2(3 x-4 t),

where

x, y

are in meter and

t

is in second. The amplitude of oscillation of particle is:

View answer and explanation

Correct option: B

7.5 m

Option B (7.5 m) is correct. By using the trigonometric identity to rewrite the equation, the amplitude of the oscillation is found to be 7.5 m.

Assertion: A particle executing simple harmonic motion comes to rest at the extreme positions.

Reason: The resultant force on the particle is zero at these positions. A particle is subjected simultaneously to two SHM’s one along the

x

-axis and the other along the

y

-axis. The two vibrations are in phase and have unequal amplitudes. The particle will execute A particle is executing SHM with amplitude
