A police jeep on a petrol duty on a national highway was moving at a speed of 54 km/hr. In the same direction. It found that a thief was rushing in a car moving at a speed of 126 km/hr. The police sub-inspector fired at the car of the thief with his service revolver with a muzzle speed of 100 m/s. with what speed will the bullet hit the car of a thief?
Step 1: Given data
Step 2: Calculating the speed
Now we'll calculate the total velocity of the bullet.
The relative velocity of bullet w.r.t. thief
Therefore the bullet will hit the car of the thief at 80 m/s.
Hence, with the speed of 80 m/s, the bullet hit the car of a thief.
