A machine gun is mounted on an armored car moving with a speed of 20 ms^(-1) . The gun point against the direction of motion of car. The muzzle speed of bullet is equal to speed of sound in air i.e., 340 ms^(-1) . The time difference between bullet actually reaching and sound of firing reaching at a target 544 m away from car at the instant of firing is reaching at a target 544 m away from car at the instant of firing is

A machine gun is mounted on an armored car moving with a speed of 20 ms^(-1) . The gun point against the direction of motion of car.
