Answer:
13.76 Joules
Explanation:
The SI units for joules are defined to be kilogram*meters per second. Therefore, we must turn the grams to kilograms by dividing the answer by 1,000. This is due to 1,000 grams being in a single kilogram. Kinetic energy is defined to be:
[tex]KE=\frac{1}{2} mv^2[/tex]
Therefore:
[tex]KE=\frac{1}{2} (0.43kg)(8m/s)^2=13.76J[/tex]
