Assertion : When a bullet is fired from a gun the bullet pierces a wooden block and stops. The temperature of the bullet and the surrounding layers of wood changes. Reason : Temperature is related to the energy of motion of the bullet as a whole.

(A) : When bullet is fired from a gun, the gunner should exert force on gun in the direction of motion of bullet. (R) : The gun recoils when bullet is fired.

When a shot is fired from a gun, the gun gets recoiled. Explain.

Name the type of energy (kinetic or potential ) possessed by a bullet fired from a gun.

Ratio of the ranges of the bullets fired from a gun ( of constant muzzle speed ) at angle theta, 2 theta &4 theta is found in the ratio x:2:2 , then the value of x will be ( Assume same muzzle speed of bullets )

A bullet is fired from the gun. The gun recoils, the kinetic energy of the recoil shall be-

A trajectory of a fighter plane is given by the relation y = x + c (when and y represents horizontal and vertical axes). The plane is moving with a constant speed of 30sqrt2 m//s . A machine gun is mounted on the plane. When the plane is at a height of 240m from the ground, a bullet is fired from the machine-gun with a speed of 10 m/s with respect to the plane in the vertical upward direction. (a) Calculate the time after which it will hit the ground (b) Find the maximum height reached by the bullet.

An earth satellite is revolving in a circular orbit of radius a with velocity upsilon_(0) . A gun in the satellite is aimed directly towards the earth. A bullet is fired from the gun with muzzle velocity (upsilon_(0))/(2) . Neglecting resistance offered by cosmic dust and recoil of gun, calculate maximum and minimum distance of bullet from the center of earth during its subsequent motion.

Assertion : A bullet is fired from a rifle. If the rifle recoils freely, the kinetic energy of rifle is more than that of the bullet. Reason : In the case of rifle bullet system the law of conservation of momentum violates.

Assertion: In case of bullet fired from gun, the ration of kinetic energy of gun and bullet is equal to ration of mass of bullet and gun. Reason: Kinetic energy prop(1)/(mass) , if momentum is constant.
