B

Statement-1 is True, Statement-2 is True and Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
A
If it is a completely inelastic collision, then `m_1v_1 + m_2v_2 = m_1v + m_2v implies `
`v = (m_1v_1 + m_2v_2)/(m_1 + m_2)`
Since v1 and v2 are in same direction, v will not be zero.
So, total KE cannot be lost.

Statement -1: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision. Statement -2 : Principle of conservation of momentum holds true for all kinds of collisions.

Assertion: There is not loss in energy in elastic collision. Reason: Linear momentum is conserved in elastic collision.

Assertion: The conservation of kinetic energy in elastic collision applies after the collision is over and does not hold at every instant of the collision. Reason: During a collision the total linear momentum is conserved at each instant of the collision.

Assertion: Separation between two bodies moving in the same direction on the ground with same acceleration, will not increase. Reason: In this case river flow helps to cross the river.

Assertion: Two bodies moving in opposite directions with same magnitude of linear momentum collide each other. Then, after collision both the bodies will come to rest. Reason: Linear momentum of the system of bodies is zero.

Assertion : In photon-particle collision the total energy and total momentum are conserved. Reason : The number of photons are conserved in a collision.

Two identical vehicles are moving with same velocity v towards an intersection as shown in figure. If the collision is completely inelastic, then

Assertion : A moving ball having an inelastic collison withh another moving ball can have larger kinetic energy after collision. Reason: During a collision between two bodies, transfer of energy mayh take place from one body to another.

A particle of mass m moving in the x direction with speed 2v is hit by another particle of mass 2m moving in they y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to :

Two particles of same mass m moving with velocities u_(1) and u_(2) collide perfectly inelastically. The loss of energy would be :
