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

D: 250m/s

 

Best Answer

 

 

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
