Answer: as we know K.E=1/2mv^2 from this eqn we get K.E is directly proportional to square of velocity ofbody so, if we triple the velocity ofbody the K.E will become nine times of the initial K.E.I hope you got it. Answer: ... The Kinetic Energy is increased by a factor of 9 if the velocity is tripled

Here is your answer....,



$question$
•what happened to the kinetic energy of a body if the velocity is tripled?




$answer$
The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. For example if the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy..

•Hence..,
The Kinetic Energy is increased by a factor of 9 if the velocity is tripled...
