Answer:
31,000 J
Explanation:
using KE = 1/2mv^2 (m stands for mass, v stands for velocity) we can do the math and the answer is 31,000J because the mass in the question listed is 155 kg and the velocity (aka speed) is 18 m/s.
kinetic energy (aka KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared.
(1/2 * 155 kg) * 18 m/s^2 = 31,000J
