Acar with a mass of 1500 kg is moving at a rate of 4 m s . determine its kinetic energy

- The Kinetic energy of the car is 12000 J.

Explanation:

Kinetic energy is the energy posessed by an object by virtue of its motion.

m= mass of object = 1500 kg

v= velocity of object = 4 m/s

Putting in the values in the equation:

Thus Kinetic energy of the car is 12000 J.

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
