A police van moving on a highway with speed 30 `kmh^-1` fires a bullet at a theif's car speeding away in the same direction with a spped of 192 `kmh^-1` . If the muzzle spped of the bullet is `150ms^-1` , at what speed does the bullet hit the thief's car?

A police van moving on a highway with speed 30 kmh^-1 fires a bullet at a theif's car speeding away in the same direction with a spped of 190 kmh^-1 . If the muzzle spped of the bullet is 360kmh^-1 , with what speed does the bullet hit the thief's car?

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^-1 . If the muzzle speed of the bullet is 150 m s^1 with what speed does the bullet hit the thief’s car ? (Note: Obtain that speed which is relevant for damaging the thief’s car).

A shell of mass 0.020 kg is fired by a gun of mass 100 kg. If the muzzle speed of the shell is 80 m s-1, what is the recoil speed of the gun?

Thief's car is moving with a speed of 10m/s . A police van chasing the car with a speed of 5 ms^-1 fires a bullet at the thief's car with muzzle velocity 72km/h. The speed with which the bullet hits the car is

Define impulse. A machine gun of 10kg mass fires 25 gm bullets at the rate of 5 bullets per second with a speed of 500 ms^(-1) . What force must be applied to the gun to hold it in position.

A car moving along a straight highway with a speed of 126 km h^-1 is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop?

A bullet of mass 50 g moving with a speed of 500 ms^-1 is brought to rest in 0.1 sec. Find the impulse and average force.

A car moving with a speed of 126 kmh^-1 is brought to stop within a distance of 200 m. What is its retardation and how long it takes for the car to stop ?

Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m s~1 collide and rebound with the same speed. What is the impulse imparted to each ball due to the other?

A trolley of mass 200 kg moves with a uniform speed of 36 km/ h on a frictionless track. A child of mass 20 kg runs on the trolley from one end to the other (10 m away) with a speed of 4 m s^-1 relative to the trolley in a direction opposite to the its motion, and jumps out of the trolley. What is the final speed of the trolley? How much has the trolley moved from the time the child begins to run?
