Question

A 14 kg object loses 525 J of gravitational potential energy. What was the change in height that the object experienced?

Answer 1

We will have the following:

$525J=(14kg)(9.8m/s^2)y\Rightarrow y=\frac{525J}{(14kg)(9.8m/s^2)}$$\Rightarrow y=\frac{375}{98}m\Rightarrow y=3.826530612\ldots m$$\Rightarrow y\approx3.8m$

So, it's heigth is approximately 3.8 meters.
