Question

Calculate the potential energy stored in an object of mass 50 kg at a height of 20 m from the ground.

Answer 1

Answer:

potential energy=mgh

=50×10×20

=10000 J

Answer 2

Answer:

$\huge\boxed{\sf P.E. = 10 kJ}$

Explanation:

Given Data:

Mass = m = 50 kg

Height = h = 20 m

Acceleration due to gravity = g = 10 m/s²

Required:

Potential Energy = P.E. = ?

Formula:

P.E. = mgh

Solution:

P.E. = (50)(20)(10)

P.E. = 10,000 Joules

P.E. = 10 * 10³ Joules (10³ = Kilo)

P.E. = 10 kJ

$\rule[225]{225}{2}$

Hope this helped!
