Question

Two bodies of a equal masses move with uniform velocity v &
3v respectively Find the ratios of their kinetic energy

Mahima Sundar · Accepted Answer

Let the first body's Kinetic energy be 1/2mv2
Let the second body's Kinetic energy be1/2m(3v)2
Ratio of their kinetic energy is
1/2mv2 /
1/2m(3v)2 = 1/9 =1:9

Two bodies of a equal masses move with uniform velocity v & 3v respectively. Find the ratios of their kinetic energy.
