    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 180m/s. The velocity with which it will strike the jeep of the thief is:

    A)  150m/5        

    B)  27m/s

    C)  450m/s          

    D)  250m/s

    Correct Answer: A

    Solution :

    The relative velocity of the ifs jeep with respect to police jeep \[=VT-VP\] Here,   \[VT=153km/h\]             \[VP=45\text{ }km/h\]             \[VTP=153-45=108\text{ }km/h\]             \[=108\times \frac{5}{18}=30m/s.\] Hence, striking speed = relative speed of bullet with respect to the ifs jeep.             \[=180-30=150m/s.\]
