Answer
The apple is traveling at 8 meters per second
Explanation
We have the equation that relates the kinetic energy with the velocty:
[tex]K=\frac{v^2}{2}[/tex]
Then, to find thevelocity when the apple has 32, we replace K = 32 j:
[tex]\begin{gathered} 32=\frac{v^2}{2} \\ 32\cdot2=v^2 \\ 64=v^2 \\ v=\sqrt{64}=8 \\ \end{gathered}[/tex]
Thus, the speed of the apple is 8meter per second
