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.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
