A police man is driving a car with a speed of 30km/h,and firing a bullet having a speed of 150m/s towards another car which is moving ahead with a speed of 192km/f.At what speed will the bullet hit the car?
v1=30km/h =30000/3600 =8.33 m/s,
v3= 192km/h =192000/3600=53.33 m/s.
v= v1+v2 =8.33+150m/s=158.33 m/s.
