1. A body A of mass 20 kg is moving with a velocity of 1 ms!. Another body B of mass 1 kg is moving with a
velocity of 20 ms. Find the ratio of kinetic energy of A and B.​

Answer 1

Answer:

1 : 20

Explanation:

$\frac{ \frac{1}{2} m1v1 {}^{2} }{ \frac{1}{2}m2v2 ^{2 } }$

$\frac{20 \times 1 \times 1}{1 \times 20 \times 20}$

1 : 20

Answer 2

Answer:

1:20 is the correct answer
