Question #1340d

Sep 8, 2017

$m = \frac{P t}{g h}$

Explanation:

$P = \frac{m g h}{t}$

$\frac{P}{1} = \frac{m g h}{t}$

Now cross multiply $t$ with $P$ and multiply $1$ with $m g h$. Then, take $m$ as common multiple and make a fraction form by dividing

$m = \frac{P t}{g h}$

We assume that the symbols used in the equation

$P = \frac{m g h}{t}$
are $P$ Power, as power is the rate of doing work.
$t$ time
$m g h$ potential energy due to gravity

As such $m =$ mass of the object under consideration.
