Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
50 kg ball traveling at 10 m/s,
A 50 kg ball traveling at 20 m/s would have
kinetic energy
A 50 kg ball traveling at 5 m/s would have
kinetic energy
A 50 kg person falling at 10 m/s would have
kinetic energy

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
