When a bomb at rest explodes into two equal parts then each part will move in a opposite directions with same velocity be opposite directions with different velocities?

A mass m moves with a velocity v and collides in elastically with another identical mass. After collision the 1st mass moves with velocity

in a direction perpendicular to the initial direction of motion. Find the speed of the second mass after collision.

A body of mass m moving with velocity v collides head on another body of mass 2m which is initially at rest. The ratio of KE of colliding body before and after collision will be

Consider the following statements A and B and identify the correct answer.

(A) In an elastic collision, if a body suffers a head on collision with another of same mass at rest, the first body comes to rest while the other starts moving with the velocity of the first one.

(B) Two bodies of equal mass suffering a head on elastic collision merely exchanges their velocities.

1 kg body explodes into three fragments. The ratio of their masses is 1: 1: 3. The fragments of same mass move perpendicular to each other with speed

while the heavier part remains in the initial direction. The speed of heavier part is

A body of mass 4 kg moving with velocity

collides with another body of mass 6 kg at rest. If two bodies stick together after collision, then the loss of kinetic energy of system is

A bomb is kept stationary at a point. It suddenly explodes into two fragments of masses 1 g and 3 g. the total KE of the fragments is

What is the KE of the smaller fragment?

A body moving with a velocity v, breaks up into two equal parts. One of the part retraces back with velocity v. Then, the velocity of the other part is

Four smooth steel balls of equal mass at rest are free to move along a straight line without friction. The first ball is given a velocity of

It collides head on with the second elastically, the second one similarly with the third and so on. The velocity of the last ball is

Consider elastic collision of a particle of mass m moving with a velocity u with another particle of the same mass at rest. After the collision the projectile and the struck particle moves in directions making angles

respectively with the initial direction of motion. The sum of the angles

Q10
