If the maximum velocity of a particle performing S.H.M. is $v$, then the average velocity during its motion from one extreme position to the other will be 

Velocity of a particle moving along a straight line at any time $t$ is given by $v=\cos \left(\frac{\pi }{3}t\right)$. Find out the distance travelled by the particle in the first two seconds.

A body is executing simple harmonic motion. At time $t$, the positon and acceleration of the body are $x\left(t\right)=x_0 \mathrm{m}$ and $a\left(t\right)=a_0 \mathrm{m} {\mathrm{s}}^{-2}$, respectively. If $x_0=a_0$, then the angular velocity (in $\mathrm{rad} {\mathrm{s}}^{-1}$)

A hydrometer executes simple harmonic motion when it is pushed down vertically in a liquid of density $\rho$. If the mass of hydrometer is $\mathrm{m}$ and the radius of the hydrometer tube is $r$, then the time period of oscillation is

The velocity of a particle executing SHM, while passing from its mean position is $V_0$. If its amplitude is doubled, without changing its period of oscillation, its velocity at the mean position will be

A body starts moving on $x$-axis from rest from $x=-2\mathrm{m}$. Acceleration $\overrightarrow{\mathrm{a}}$ of the particle varies according to the equation

$\overrightarrow{a}=-{\left(\pi \mathrm{rad} {\mathrm{s}}^{-1}\right)}^2\left(\overrightarrow{x}\right)$ for $0\le t\le \frac{1}{2}\mathrm{s}$

$\overrightarrow{a}=\left(5\pi \mathrm{m} {\mathrm{s}}^{-2}\right)\left(\hat{x}\right)$ for, $t>\frac{1}{2} \mathrm{s}$

Where $\overrightarrow{x}$ is the position vector of the particle at any instant $t$. Then velocity of the particle at $\mathrm{x}=\frac{\pi }{2} \mathrm{m}$ is

If $y=A\sin \left(kx-\omega t\right)$, then find $\frac{{\displaystyle \frac{dy}{dx}}}{{\displaystyle \frac{dy}{dt}}}$.

Find $\left(v\right)$ and $\left(a\right)$ in following equation of SHM.

The displacement of two particles executing S.H.M are represented by $y_1=a\sin \omega t$ and $y_2=a\cos \left(\omega t+\varphi \right)$. The phase difference between the velocities of these particles is

In the figure shown two motors $P_1 \& P_2$ fixed on a plank which is hanging with light string passing over fixed Pulley $P$. If the motors starts winding the thread with angular velocity ${\omega }_1$ & ${\omega }_2$ then velocity of plank $V$ is (here $R_1 \& R_2$ are the radii of motor rotor respectively) [Given: ${\omega }_1=2 \mathrm{rad} {\mathrm{s}}^{-1}, R_1=2 \mathrm{m}, {\omega }_2=2 \mathrm{rad} {\mathrm{s}}^{-1}, R_2=3 \mathrm{m}$]

The relation between the acceleration $\text{'}a\text{'}$ and displacement $\text{'}y\text{'}$ of a particle executing SHM is a $a=-\frac{p}{q}y$, where $p$ and $q$ are constants. What will be the time period $T$ of the particle?

Which one of the following is the correct acceleration vs. time graph for a particle performing SHM?
