Question

an object has a kinetic energy of 36 j. if the object's speed is tripled, then its new kinetic energy will be .

Answer 1

new kinetic energy k2=324 J.

given data:-

kinetic energy k1=36

kinetic energy k2= k2

mass =m kg

velocity v1= v m/s

if the object's speed is tripled than mew v= 3*v1

(36=1/2mv1)/(k2=1/2m3v1)

k2= 36*9

then the kinetic energy will be=324 J.

When the kinetic energy of mass and speed is tripled, what happens?

Therefore, if the mass triples, the KE will also triple. Kinetic energy and velocity have a straight proportional relationship, although it is with the square of the velocity. In the event that the velocity triples, the result is 32, three squared, or 9. KE is therefore nine times larger.
