Answer:

The kinetic energy of the roller coaster is 1600000 J.

Step-by-step explanation:

Given:

Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.

Now, we need to find the kinetic energy E_{k} of the roller coaster.

So, Mass of roller coaster (m) = 8000 N.

Velocity of roller coaster (v) = 20.0 m/s.

Now, putting the formula of kinetic energy:

E_{k} = \frac{1}{2}\times m\times v^{2}

E_{k}=\frac{1}{2} \times 8000\times 20^{2}

E_{k}=\frac{1}{2} \times 8000\times 400

E_{k}=\frac{1}{2} \times 3200000

E_{k}=1600000

Therefore, the kinetic energy of the roller coaster is 1600000 J.
