Answer:
1. The elephant has more kinetic energy at this speed and mass. It has 4,500 J more KE.
2. The elephant would have to go at a speed of 2.5 m/s to reach the same KE as the cheetah.
Explanation:
You would use the formula KE=1/2mv^2.
This formula would be filled in and completed twice, once for the elephant and once for the cheetah.
Cheetah:
KE = 1/2 (40) (25) ^2
KE = 12,500 J
Elephant:
KE = 1/2 (4,000) (2) ^2
KE = 8,000 J
This shows that the cheetah has more KE.
Then you would subtract the elephants amount of J from the cheetahs to find the difference.
Difference = 12,500 J - 8,000 J
Difference = 4,500 J
I hoped this helped with the first part :)
For the second part:
To find the speed the elephant would have to run you would fill in and complete the equation once more with different distance results.
KE = 1/2 (4,000) (2.5) ^2
KE= 12,500 J
Satellites would be able to detect fires when they start and allow human monitors to review the information and issue warnings.
Using the definition of kinetic energy, we have:
Protons and neutrons are in the center of the atom, making up the nucleus. The proton and electron are exactly the same size but different,Since the difference charges attract, protons and electrons attract each other.
The Stratosphere contains the highest concentration of the ozone, this is because the ozone is located here. The Thermosphere has the highest average air temperature also seen as the hot layer, and the Mesosphere is the lowest average sir temperature.
