Question

if mass becomes 2 times and and velocity becomes 1/3 then the kinetic energy will be ?​
sorry the question is of stream science

Answer 1

Explanation:

Kinetic energy is derived using formula 1/2mv^2

If mass becomes 2 times, it will become 2m

If velocity becomes one third, it will become v/3

Substituting in the equation:-

1/2× 2m × (v/3) ^2

m×v^2/9

mv^2 / 9, Which gives the kinetic energy of the body.

Hope this helped!
