Question

How fast is the apple traveling when the kinetic energy is 32 joules?

Answer 1

The apple is traveling at 8 meters per second

Step-by-step explanation

We have the equation that relates the kinetic energy with the velocty:

`K=(v^2)/(2)`

Then, to find thevelocity when the apple has 32, we replace K = 32 j:

`\begin{gathered} 32=(v^2)/(2) \\ 32\cdot2=v^2 \\ 64=v^2 \\ v=√(64)=8 \\ \end{gathered}`

Thus, the speed of the apple is 8meter per second
