Answer:

Hence, kinetic energy = 25 × 4 = 100 J. (ii) If velocity is increased three times, then its kinetic energy becomes 9 times the original value, because it is proportional to the square of the velocity. Hence, kinetic energy = 25 × 9 = 225 J.

Answer:

kinetic energy = 25 × 4 = 100 J.

If velocity is increased three times,

then its kinetic energy becomes 9 times the original value,

because it is proportional to the square of the velocity.

Hence, kinetic energy = 25 × 9 = 225 J.
