1.	A ball rolls off the top of a stairway horizontally with a velocity of 5 m/s. Each step is 0.1 m high and 0.1 m wide. If g=10 m/s2 and the ball strikes the nth step, then find the value of n.
Answer» A ball rolls off the top of a stairway horizontally with a velocity of $5 m/s$ . Each step is $0.1 m$ high and $0.1 m$ wide. If $g = 10 {m/s}^{2}$ and the ball strikes the $n^{t h}$ step, then find the value of $n$ .

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?
