Work Energy And Power Question 59

Question: If a lighter body (mass M1 and velocity V1 ) and a heavier body (mass M2 and velocity V2 ) have the same kinetic energy, then [MP PMT 1997]

Options:

A) M2V2<M1V1

B) M2V2=M1V1

C) M2V1=M1V2

D) M2V2>M1V1

Show Answer

Answer:

Correct Answer: D

Solution:

P=2mE. If kinetic energy are equal then

Pm i.e., heavier body posses large momentum .

As M1<M2 therefore M1V1<M2V2
