Question

Which one(s) of the following statements is (are) correct for INELASTIC collision between two objects?

a- The amount of kinetic energy lost by one object is the same as the amount of kinetic energy gained by the other object

b- Neither the total momentum nor the total kinetic energy is conserved.

c- Total momentum is conserved, but total kinetic energy is notconserved.

d- Both the total momentum and the total kinetic energy areconserved.

e- The magnitude of the momentum lost by one object is the same as the magnitude of the momentum gained by the other object

f- Total momentum is not conserved, but total kinetic energy is conserved.

*** there is more than one answer. i know that (C) is correct already

The correct options are (c) and (e). I am using kinetic energy= KE

In inelastic collision, the total momentum is conserved while total KE is not conserved.

a) It is incorrect as the amount of KE lost by one is gain by another by same amount shows that there is no change in total KE.

Thus, total KE is same i.e. conserved.

b) It is incorrect as the total momentum is remain conserved.

c) It is correct as total momentum is conserved but total KE is not conserved.

d) It is incorrect as total KE is not conserved.

e) It is correct as the momentum lost by one object is gained by another by same amount so there is no change in total momentum.

Thus, total momentum is conserved.

f) It is incorrect as total momentum is conserved but total KE is not conserved.
