1.	Two cars A and B are moving west to east and south to north respectively along crossroads. A moves with a speed of 72 kmh−1 and is 500 m away from point of intersection of crossroads and B moves with a speed of 54 kmh−1 and is 400 m away from point of intersection of crossroads. Find the shortest distance between them in metres?
Answer» Two cars $A$ and $B$ are moving west to east and south to north respectively along crossroads. $A$ moves with a speed of $72 {kmh}^{- 1}$ and is $500 m$ away from point of intersection of crossroads and $B$ moves with a speed of $54 {kmh}^{- 1}$ and is $400 m$ away from point of intersection of crossroads. Find the shortest distance between them in metres?

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?
