Gravitational Potential Energy of an object is calculated by formula ~

[tex] \large\boxed{\sf P = mgh}[/tex]

where,

  • m = mass of the object = 3500 kg

  • g = Acceleration due to gravity = 12 m/s²

  • h = height attained by the object = 4 m

Now, let's calculate its potential energy ~

  • [tex]3500 \times 10 \times 4[/tex]

  • [tex]140000 \: \: joules[/tex]

  • [tex]140 \: \: kj[/tex]

Answer:

Potential Energy of an object is calculated by formula:

  • Potential Energy (P.E)=m×g×h

Where,

  • m=mass of body
  • g=acceleration due to gravity
  • h=height from the earth surface

Now, let's solve the question.

Given,

  • mass(m)=3500 kg
  • height (h)=4m
  • velocity (v)=10m/s²

Now,

We know that,

Potential Energy (P.E)=mgh

[tex] = 3500 \times 10 \times 4[/tex]

[tex] = 3500 0\times 4[/tex]

[tex] =140000 joules [/tex]
