A bomb of mass 3.0 kg explodes in air into two pieces of masses 2.0 kg and 1.0 kg. The smaller mass goes at a speed of 80 m/s. The total energy imparted to the two fragments is

The spheres A and B masses m₁ and m₂ respectively collide. A is at rest initially and B is moving with velocity v along x-axis, After collision B has a velocity v/2 in a direction perpendicular to the original direction.The mass A moves after collision in the direction

A shell initially at rest explodes into two pieces of equal mass, then the two pieces will

A lead ball strikes a wall and falls down, a tennis ball having the same mass and velocity strikes the wall and bounces back. Check the correct statement

A sphere collides with another sphere of identical mass. After collision, the two spheres move. The collision is inelastic. Then the angle between the directions of the two spheres is

A gun fires a bullet of mass 50 g with a velocity of 30 m sec^–1. Because of this the gun is pushed back with a velocity of 1 m sec^–1. The mass of the gun is

A smooth sphere of mass M moving with velocity u directly collides elastically with another sphere of mass m at rest. After collision their final velocities are V and v respectively . The value of v is

A body of mass m having an initial velocity v, makes head on collision with a stationary body of mass M. After the collision, the body of mass m comes to rest and only the body having mass M moves. This will happen only when

A particle of mass m moving with horizontal speed 6 m/sec as shown in figure. If m << M then for one dimensional elastic collision, the speed of lighter particle after collision will be

A shell of mass m moving with velocity v suddenly breaks into 2 pieces. The part having mass m/4 remains stationary. The velocity of the other shell will be
