If the speed of an object were to triple, what would be the increase of kinetic energy?
KE↓2=_____KE↓1

1. 1/3
2. 1/9
3. 3
4. 9

Respuesta :

Answer:

4. 9

Explanation:

For instance, if the speed of an object becomes double, its kinetic energy changes to four times the initial kinetic energy.Similarly, if the speed of the object triples the kinetic energy becomes nine times the initial kinetic energy.

Therefore the answer is 9.
