Answer:
The one with the full load.
Explanation: We can prove this by doing V^2 X M = KE
where V= velocity M= mass and KE= kinetic energy.
is both are traveling at the same speed (let's say 2kmph) and one has a mass of 50 kg with the other having a mass of 100kg.
(plug in the values) . 2^2 X 50 = KE and 2^2 X 100= KE
(simplify) 200=KE and 400=KE
This proves that a dump truck with a larger load (if traveling at the same speed) will always contain more energy than a dump truck with a smaller load.
