Two students both kick a soccer ball. Havanna's ball travels three times as fast at Mitzi's ball. How does the kinetic energy of the two soccer balls compare?

The kinetic energy of Havanna's ball is 9 times the kinetic energy of Mitzi's ball.

Explanation:

Let the velocity of Mitzi's ball = v₁

then, the velocity of Havanna's ball = 3v₁

Kinetic energy is given as;

K.E = ¹/₂mv²

Where;

m is mass of the object

v is velocity of the object

Kinetic energy of Mitzi's ball is given by;

K.E(m) = ¹/₂mv₁²

kinetic energy of Havanna's ball is given by;

K.E(H) = ¹/₂m(3v₁)²

K.E(H) = ¹/₂m x 9v₁²

K.E(H) = 9(¹/₂mv₁²)

K.E(H) = 9(K.E(m) )

Therefore, the kinetic energy of Havanna's ball is 9 times the kinetic energy of Mitzi's ball.

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
