What is the potential energy of a car with a mass of 1200kg at the top of a 42m high hill?

P.E = 493920 j

Explanation:

Given data:

Mass = 1200 kg

height = 42 m

Potential energy = ?

Solution:

Formula:

P.E = mgh

Now we will put the values in formula.

g = 9.8 m/s²

P.E = 1200 Kg × 9.8 m/s²× 42 m

P.E = 493920 Kg.m²/s²

Kg.m²/s² = j

P.E = 493920 j

explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
