To find the kinetic energy of the roller-coaster at the bottom of the hill, we can use the equation:
KE = 1/2 * m * v^2
where KE is the kinetic energy, m is the mass, and v is the velocity.
Given:
Mass (m) = 1088 kg
Velocity (v) = 33 m/s
Plugging in these values into the equation, we have:
KE = 1/2 * 1088 kg * (33 m/s)^2
KE β 592,416 J
Therefore, the correct answer is 592,416 J.
