If the velocity of a body is increased 3 times what happens to its kinetic energy
Original Velocity = v
Original K.E. = 1/2 mv2
Now, new velocity = 3v
New K.E. =1/2m(3v)2
=1/2mv2 * 9
= 9 times original K.E.
Original K.E. = 1/2 mv2
Now, new velocity = 3v
New K.E. =1/2m(3v)2
=1/2mv2 * 9
= 9 times original K.E.
