How much kinetic energy does a truck with a mass of 2500 kg moving at 45 m have

Kinetic energy,

Explanation:

We have,

Mass of the truck is 2500 kg. It is moving with a speed of 45 m/s.

It is required to find the kinetic energy acting on the truck. As it is moving with some velocity, it will have kinetic energy. The kinetic energy of an object is given by :

, m is mass and v is velocity

So, the kinetic energy of the truck is .

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
