$(a)$ the period of oscillation.

$(b)$ the maximum speed and

$(c)$ maximum acceleration of the collar.

$(a)$ The period of oscillation 

$T=2 \pi \sqrt{\frac{m}{k}}=2 \pi \sqrt{\frac{5.0\, kg }{500\,N\,m^{-1}}}$

$=(2 \pi / 10)\, s$

$=0.63 \,s$

$(b)$ The velocity of the collar executing $SHM$ is given by

$v(t)=-A \omega \sin (\omega t+\phi)$

The maximum speed is given by,

$v_{m}=A \omega$

$=0.1 \times \sqrt{\frac{k}{m}}$

$=0.1 \times \sqrt{\frac{500\, N m ^{-1}}{5\, kg }}$

$=1 \,m s ^{-1}$

and it occurs at $x=0$

$(c)$ The acceleration of the collar at the displacement $x(t)$ from the equilibrium is given by,

$a(t) =-\omega^{2} x(t)$

$=-\frac{k}{m} x(t)$

Therefore, the maximum acceleration is $a_{\max }=\omega^{2} A$

$=\frac{500\, N \,m ^{-1}}{5 \,kg } \times 0.1 \,m$

$=10\, m s ^{-2}$

and it occurs at the extremities.

How the period of oscillation depend on the mass of block attached to the end of spring ?

A mass $M$ is suspended from a light spring. An additional mass m added displaces the spring further by a distance $x$. Now the combined mass will oscillate on the spring with period

A block of mass $m$ is at rest on an another block of same mass as shown in figure. Lower block is attached to the spring, then the maximum amplitude of motion so that both the block will remain in contact is

Two bodies $M$ and $N $ of equal masses are suspended from two separate massless springs of force constants $k_1$ and $k_2$ respectively. If the two bodies oscillate vertically such that their maximum velocities are equal, the ratio of the amplitude $M$ to that of $N$ is
