Ball b has eight times more kinetic energy than ball a, which has half its mass. The speed ratio is 4.
<h3>What exactly does kinetic energy mean?</h3>Force must be applied to object in order to accelerate. To apply a force, we must work hard. Because energy has been transferred to the object, it will be moving at a new, constant speed once the operation is finished.
Given,
Two balls a and b
and the mass of ball an is half that of ball b..
Kinetic energy of ball a is eight times kinetic energy of ball b.
mₐ =
KEₐ = 8 KE
Kinetic energy is measured by,
KE = 1/2 mv²
KE ratios for both balls a and b are calculated,
∴ =
=
16 =
= 4/1
