A body of mass $1kg$ is made to oscillate on a spring of force constant $16N/m.$ Calculate:

1.angular frequency.

2.the frequency of vibration.

Q. If a body of mass $0.98kg$ is made to oscillate on a spring of force constant $4.84N/m$, the angular frequency of the body is

Q. A mass m is suspended from a spring of force constant $k.$ The angular frequency of oscillation of the spring will be

Q. Two springs, of force constant $k_1$ and $k_2$, are connected to a mass m as shown. The frequency of oscillation of the mass is $f$. If both $k_1$ and $k_2$ are made four times their original values, the frequency of oscillation becomes

Q. On suspending a mass M from a spring of force constant K,frequency of vibration f is obtained If a second spring as shown in the figure. is arranged then the frequency will be :

Q. A body of mass $1kg$ is suspended from a weightless spring having force constant $600N/m$. Another body of mass $0.5kg$ moving vertically upwards hits the suspended body with a velocity of $3.0m/s$ and get embedded in it. Find the frequency of oscillations and amplitude of motion.
