Question

If 2 J of work is done in raising a 0.180 kg red delicious apple to bring it to your mouth to take a bite of the apple, how far is it lifted

Answer 1

Given that the work done in raising the apple is W = 2 J

Also, the mass of apple is m = 0.180 kg

We have to find the distance traveled by the apple.

As the work done = potential energy.

Work done will be equal to mgh.

Here, g = 9.8 m/s^2 is the acceleration due to gravity.

h is the distance traveled by the apple.

So the distance traveled by the apple will be

`\begin{gathered} W=\text{ mgh} \\ h=(W)/(mg) \\ =(2)/(0.18*9.8) \\ =\text{ 1.134 m} \end{gathered}`

Thus, the apple is lifted 1.134 m.
