Answer:

6,000,000 J (6 million)

Explanation:

Refer to the equations for potential and kinetic energy.

[tex]KE = \frac{1}{2}mv^{2}\\PE = mgh[/tex]

Because the automobile is on the ground (it does not give a height above the ground, therefore we can assume that it is on the ground), height = 0.  If you plug in 0 for h in the potential energy equation, we get PE = 0 J.

Therefore, all of the energy is kinetic.  Plug in the given information into the kinetic energy equation.  M = 1200 kg and v = 100 m/s

[tex]KE = \frac{1}{2}mv^{2} = \frac{1}{2}(1200)(100^{2}) = 6,000,000\ J[/tex]

The energy possess is 6,000,000 J

The kinetic energy is a energy by which an object can move and potential energy is a stored energy which depends upon the relative position of various parts of the body.

Given:

The mass of automobile is [tex]m=1200\:\rm kg[/tex].

The velocity of the automobile is [tex]100\;\rm m/s[/tex].

How to calculate potential energy and kinetic energy?

Write the formula to calculate the potential energy of the body.

[tex]P.E=mgh[/tex]

Since the automobile is on ground so the height [tex]h[/tex] will be 0.

[tex]P.E=1200\times 9.81\times 0\\P.E=0[/tex]

Write the formula to calculate the kinetic energy.

[tex]K.E=\dfrac{1}{2}mv^2[/tex]

Substitute the value.

[tex]K.E=\dfrac{1}{2}\times 1200\times 100^2\\K.E= 6,000,000 J.[/tex]
