Question

What is the kinetic energy of a 155 kg object that is moving with a speed of 18 m/s? With Details.

Answer 1

Kinetic energy = 1/2 * mass * velocity^2 so Ke = 1/2*(155*10^3 g)*18^2 which is 25,110,000 joules.

Answer 2

31,000 J

Step-by-step 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
