1.	A player kicks a football at an angle of 45∘ with a velocity of 20 ms−1. A second player 60 m away along the direction of kick starts running to receive the ball at that instant. Find the speed with which second player should run to reach the ball before it hits the ground (g=10 ms−2)
Answer» A player kicks a football at an angle of $45^{\circ}$ with a velocity of $20 m s^{- 1}$ . A second player $60 m$ away along the direction of kick starts running to receive the ball at that instant. Find the speed with which second player should run to reach the ball before it hits the ground $(g = 10 m s^{- 2})$

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?
