Question

Calculate The Kinetic Energy Of An Object When it's Mass Become three times​

Answer 1

Answer:

The kinetic energy of an object of mass, m moving with a velocity of 5 m s-1 is 25 J. ... Hence, kinetic energy = 25 × 4 = 100 J. (ii) If velocity is increased three times, then its kinetic energy becomes 9 times because it is proportional to the square of the velocity. Hence, kinetic energy = 25 × 9 = 225 J.
