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

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
