Question

What is the kinetic energy of an object that has a mass of 30 kilograms and moves with a velocity of 20 m/s? A. 12,000 J B. 5,880 J C. 6,000 J D. 2,940 J
PLZ HELP

Answer 1

m = 30 kg.

v = 20 m/s.

So, Kinetic Energy (K) = (m×v^2)/2

K = (30 × 20 × 20)/2

K = 12000/2

K = 6000 Joule....●
