What's the formula for potential energy?

[molten sable]

E.p= m X g Xh

[molten sable]

E.p= m X g Xh

[midnight rune]

Yep so

Mass of the car = m = 905 kg

g = 9.8 m/s² is what it seems you've taken.

When it started, it was at a height of 1080 m

[molten sable]

yes

[midnight rune]

So, plug in these values in the formula.

After reaching the place,

[molten sable]

wouldn’t we subtract the height?

[midnight rune]

I am actually preferring you to do
mgh1 - mgh2

Where h1 and h2 are final and initial heights.

But yes, you can also do mg(h1 - h2).

,calc 905 * 9.8 * (4080-1860)

[digital bolt]

Result:

1.968918e+7

[midnight rune]

Eh

[molten sable]

exactly that’s pretty much what i got

& for the second question

is this correct?

[midnight rune]

First is correct then. Reading the second one now.

Okay sorry, had to go.

[molten sable]

okay so…??

[midnight rune]

So

10 percent would be

[molten sable]

YES

[midnight rune]

18 km

[molten sable]

yes, that is our height

[midnight rune]

,calc 1.48 * 10^7/(9.8 * 18000)

[digital bolt]

Result:

83.90022675737

[midnight rune]

This should be the mass.

In kg

Because all the units used are in SI.

I converted height into metres as well.

[midnight rune]

You forgot to change your 18km into metres.

[molten sable]

yeah the what i thought

that’s what i also said to the person who helped me

@midnight rune thank you for your assistance it is greatly appreciated
