Question

When the velocity of body is tripled then kinetic energy

Answer 1

Answer:

When velocity of body is tripled then k.e. gets divided by 9.

Explanation:

1/2 mv²=K.E

K.E = 1/2m(3v)²

=K.E/9

Answer 2

Answer:

Explanation: We know that...

Kinetic Energy = 1/2 mv² where v is velocity...

So if velocity is tripled then..-

K.E= 1/2 m (3v)²

= 1/2 m 9v² or 9 (1/2 mv²) i.e. 9 KE
