Using Einstein's formula if an object has a mass of 300kg what is its energy?

Answer 1

according to Einstein

E=mc2

OR

Energy=mass*the speed of sound2

Where the speed of sound is 3x108m/s (300,000,000m/s).

Thus, if the mass is 300kg:

E=300*300,000,000 (Joules or J)

E=90,000,000,000 J

OR

E=90GJ

according to Einstein

E=mc2

OR

Energy=mass*the speed of sound2

Where the speed of sound is 3x108m/s (300,000,000m/s).

Thus, if the mass is 300kg:

E=300*300,000,000 (Joules or J)

E=90,000,000,000 J

OR

E=90GJ

Answer 2

To find the energy of an object using Einstein's formula (E=mc^2), first convert mass from kg to kg (1 kg = 1000 g) and light speed (c) is 3x10^8 m/s. Then, substitute the values into the formula E=mc^2 to calculate the energy. The energy of an object with a mass of 300 kg would be E = 300 kg x (3 x 10^8 m/s)^2.
