Question

(xii) If mass and speed both are doubled, the kinetic energy will be:
*double *four times *six times *eight times

Answer 1

Answer:

If the mass and speed both are doubled the kinetic energy wil be eight times.

Explanation:

mass=2m

speed=2v so,

Kinetic energy =1/2×2m(2v)²

=8(1/2mv²)

8 times kinetic energy
