Answer
Kinetic energy of acorn is 0.375 J .
Explanation:
Formula
Kinetic energy is defined by
[tex]K.E = \frac{1}{2}mv^{2}[/tex]
Where m is mass and v is velocity .
As given
An acorn with a mass of 0.0300 kilograms falls from a tree with a velocity of 5.00 m/s .
m = 0.0300 Kg
v = 5 m/s
Putting all the values in the formula
[tex]K.E = \frac{1}{2}\times 0.0300\times 5\times 5[/tex]
[tex]K.E = \frac{1\times 0.0300\times 5\times 5}{2}[/tex]
[tex]K.E = \frac{0.75}{2}[/tex]
K.E = 0.375 J
Therefore the kinetic energy of acorn is 0.375 J .
