Maximum transfer of energy

Question

A body of mass M1 collides elastically  with another mass M2 at rest .  there  is maximum  transfer  of energy

A) M1》M2

B) M1《M2

C)  M1=M2

D) same for all values  of M1 andM2

Answer 1

Answer: C)  M₁=M₂

Transfer will be maximum when both masses are equal and one is at rest.

Answer 2

The Correct option is C) M₁ = M₂

Explanation:

Kinetic energy of M₁ before collision 

Kinetic energy of M₁ after collision 

Kinetic energy transferred from M1 to M2, ΔK = decrease in kinetic energy in projectile

So, Remember,

Transfer of energy will be maximum if the difference between the masses is minimum.

If M1 = M2

So, if M1 and M2 are equal then there will be maximum possible transfer of energy.
