A particle executes simple harmonic oscillation with an amplitude $A$. The period of oscillation is $T$. The minimum time taken by the particle to travel half of the amplitude from the equilibrium position is:
Out of the following functions, which represents SHM? I. $y = \sin \omega t - \cos \omega t$ II. $y = \sin^3 \omega t$ III. $y = 5 \cos\left(\frac{3\pi}{4} - 3\omega t\right)$ IV. $y = 1 + \omega t + \omega^2 t^2$
A body of mass $m$ is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass $m$ is slightly pulled down and released, it oscillates with a time period of $3\text{ s}$. When the mass $m$ is increased by $1\text{ kg}$, the time period of oscillations becomes $5\text{ s}$. The value of $m$ in kg is:
