. A police jeep is chasing with velocity of 45km/h a thief in another jeep moving with velocity 153km/h

Police fires a bullet with muzzle velocity of 180m/s. The velocity it will strike the car of the thief is?

A: 150m/s

B: 27m/s

C: 450m/s

D: 250m/s

Explanation:

The effective speed of the velocity will be

=Speed of the bullet + speed of the jeep

=(180m/sec + 45km/hr)

=180+(45 x 5/18)m/sec

=192.5m/sec

So the speed of thief’s jeep =192.5m/sec-153km/hr

=192.5-42.5m/sec

=150m/sec

Correct Option is: (A)

150m/s
