Question

a body of mass 4 kg is freely dropped from a height 180 metres to the ground is equal to 10 metre per second square then potential energy maximum height is ​

Answer 1

Answer:

Ans-7200 J

Explanation:

Write ur q. carefully.... many grammatical mistakes that can't be recognised.

So and...

Now..

Answer----¡¡I

$mass \: of \: the \: body = 4kg$

$height = 180m$

$g = 10 {ms}^{ - 1}$

So..

as Potential energy=

$m.g.h$

So ... substituting the values ... we get ..

Potential energy =

$4 \times 180 \times 10$

$i.e. = 7200$

And since its energy ... so answer is in Joules...

So answer is 7200J
