A mass attached to a spring oscillates with a period of 22 sec. After 22 kg are​ added, the period becomes 33 sec. Assuming that
polet [3.4K]

Answer:

Mass of 17.854 kg is only attached to the spring    

Explanation:

We have given time period in first case is 22 sec

Let initially mass is m

After 22 kg are added the period becomes 33 sec

Time period of spring mass system is

T=2\pi \sqrt{\frac{m}{k}}, here m is mass and k is spring constant

From the relation we can see that

\frac{T_1}{T_2}=\sqrt{\frac{m}{m+22}}

\frac{22}{33}=\sqrt{\frac{m}{m+22}}

Squaring both side

0.444={\frac{m}{m+22}}

0.444m+9.777=m

m = 17.584 kg

So mass of 17.854 kg is only attached to the spring
