Question

(iii) The kinetic energy of an object of mass (m) moving with a velocity of 5m/s
is 25 J. What will be its kinetic energy when its velocity is doubled​

Answer 1

Answer:

and then I can see the full address of the most important thing

Answer 2

Answer:

If the velocity of an object is doubled, then its kinetic energy becomes 4 times the original value, because it is proportional to the square of the velocity. ... Hence, kinetic energy = 25 × 9 = 225 J.
