    A police Jeep is chasing with velocity of 45 km/h a thief in another jeep moving with velocity 153 km/h. Police fires a bullet with muzzle velocity of 180 m/s. The velocity with which it will strike the car of the thief is:

    A)  150 m/s

    B)         27 m/s                

    C)         450 m/s                              

    D)         250 m/s

    Correct Answer: A

    Solution :

                                    The relative velocity of thiefs jeep with respect to police jeep                 \[=153-45\]                 \[=108\,\,km/h\]                 \[=108\times \frac{5}{18}m/s\]                 \[=30\,\,m/s\] Therefore, sinking speed = relative speed of bullet with respect to thiefs car                 \[=180-30\]                 \[=150\,\,m/s\]
