A particle is executing the motion $x = A\cos (\omega \,t - \theta )$. The maximum velocity of the particle is
A$A\omega \cos \theta $
B$A\omega $
C$A\omega \sin \theta $
D
None of these

B$A\omega $
b Velocity of a particle executing SHM is given by,
$v =\omega \sqrt{ A ^2- x ^2}$
For maximum velocity we need $x=0$. So, by putting $x=0$ in equation $(1)$ we have,
$v_{\max }=A \omega$ which is our required answer.

Acceleration $A$ and time period $T$ of a body in $S.H.M.$ is given by a curve shown below. Then corresponding graph, between kinetic energy $(K.E.)$ and time $t$ is correctly represented by
Time period of a simple pendulum in a stationary lift is ' $T$ '. If the lift accelerates with $\frac{ g }{6}$ vertically upwards then the time period will be .....
Let $T_1$ and $T_2$ be the time periods of two springs $A$ and $B$ when a mass $m$ is suspended from them separately. Now both the springs are connected in parallel and same mass $m$ is suspended with them. Now let $T$ be the time period in this position. Then
Three simple harmonic motions in the same direction having the same amplitude a and same period are superposed. If each differs in phase from the next by ${45^o}$, then
When a mass $M$ is attached to the spring of force constant $k$, then the spring stretches by $l$. If the mass oscillates with amplitude $l$, what will be maximum potential energy stored in the spring
A light balloon filled with helium of density $\rho_{ He }$ is tied to a long light string of length $l$ and the string is attached to the ground. If the balloon is displaced slightly in the horizontal direction from the equilibrium and released. Then,
