Answer:
The kinetic energy is 20,000\ J
Step-by-step explanation:
The kinetic energy of a body is defined as:
Where <em>m</em> is the mass of the roller coaster car
<em>s</em> is the speed and <em>k</em> is the kinetic energy
We know that 
Then the kinetic energy of the roller coaster car is:
56x^2+6x-36 bc of the FOIL METHOD which goes multiple first term, outer terms, inner terms, and last terms
