PHXI06:WORK ENERGY AND POWER

355252 Assertion :
Kinetic energy is conserved at every instant of elastic collision.
Reason :
Deformation of matter occurs at some instant of elastic collision.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI06:WORK ENERGY AND POWER

355253 Assertion :
If two bodies of equal masses undergo elastic collision in one dimension, then after the colision, the bodies will exchange their velocities.
Reason :
In elastic collision, velocity of approach is not equal and opposite of velocity of separation.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI06:WORK ENERGY AND POWER

355254 A block \(C\) of mass \(m\) is moving with velocity \(v_{0}\) and collides elastically with block \(A\) of mass \(m\) and connected to another block \(B\) of mass \(2 m\) through spring of spring constant \(k\). What is the value of \(k\), if \(x_{0}\) is compression of spring when, velocity of \(A\) and \(B\) is same?
