1.	A disc of mass m is moving with constant speed v0 on a smooth horizontal table. Another disc of same mass is placed on the table at rest as show in the figure. If collision is elastic then find the velocity of the discs after collision.[Consider r<<R](θ = tan−1h√R2−h2).
Answer» A disc of mass $m$ is moving with constant speed $v_{0}$ on a smooth horizontal table. Another disc of same mass is placed on the table at rest as show in the figure. If collision is elastic then find the velocity of the discs after collision. [Consider $r << R$ ] $(θ = t a n^{- 1} \frac{h}{\sqrt{R^{2} - h^{2}}})$ .

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
