A police van moving on a highway with a speed of 30 km $h^{- 1}$ fires a bullet at a thief's car speeding away in the same direction with a speed of 192 km ${h r}^{- 1}$ , If the muzzle speed of the bullet is 150 ${m s}^{- 1}$ , with what speed does the bullet hits the car ?

Solution

the velocity with which the bullet hits the car is,

= speed of police van + speed of the bullet - speed of the thief's car

$= 30 \times \frac{1000}{3600} + 150 - 192 \times \frac{1000}{3600}$

$= 8.33 + 150 - 53.33$

$= 105 m / s$

A police van moving on a highway with a speed of 30 km h−1 fires a bullet at a thief's car speeding away in the same direction with a speed of 192 km hr−1, If the muzzle speed of the bullet is 150ms−1, with what speed does the bullet hits the car ?

the velocity with which the bullet hits the car is,= speed of police van + speed of the bullet - speed of the thief's car=30×10003600+150−192×10003600=8.33+150−53.33=105m/s
