Maximum acceleration of an object in simple harmonic motion is 24 $$m/s^2$$ and maximum velocity is 16 m/sec. The amplitude of object is 

The time taken by block-bullet system to move from $$y = \dfrac { m g } { k }$$ (initial equilibrium position) to $$y = 0$$ (natural length of spring) is ($$A$$ represents the amplitude of motion).

A person observe two points on a string as a travelling wave passes them. The points are at $$x _ { 1 } = 0$$ and $$x_2 = 1m$$. The transverse motions of the two points are found to be as follows: $$y _ { 1 } = 0.2 \sin 3 \pi t$$
$$y _ { 2 } = 0.2 \sin ( 3 \pi t + \pi/8 )$$ What is the frequency in $$Hz$$?

A wave pulse is given by the equation $$y=f(x,t)=A exp(-B(x-vt)^{2})$$. Given $$A=1.0m.B=1.0m^{-2}$$ and $$v=+2.0m/s$$. which of the following graph shows the correct wave profile at the instant $$t=1s$$?

A particle starts from the origin, goes along $$X-$$ axis to the point $$(20\ m,\ 0)$$ and then returns along the same line to the point $$(-20m,\ 0)$$. The distance and displacement of the particle during the trip are

A particle executes simple harmonic motion with a time period of 16 s. At time t=2s, the particle crosses the mean position. Its velocity is $$4 ms^{-1}$$ when t=4s. The amplitude of motion is 

A particle executes SHM with a time period of 16 second .at time t is equal 2 second the particle crosses the mean position while at t is equal to 4 second its velocity is 4 m per second the amplitude of motion in metre is

The distance between consecutive maxima and minima is given by

The amplitude of a wave represented by displacement equation :
$$ y=\frac { 1 }{ \sqrt { a }  } sin\omega t\pm \frac { 1 }{ \sqrt { b }  } cos\omega t $$ will be :

A body is performing linear SHM, If the displacement, acceleration and the corresponding velocity of the body are y, 'a' and v respectievly, which of the following graphs is/are correct?
