Question

an object of mass 1kg was at rest before it fell through a height o 5m and hit the ground. Calculate the initial gravitational potential energy of the object

Answer 1

Hello!

Data:

h = 5 m

m = 1 Kg

PE = ? (Joule)

Adopting, gravity (g) ≈ 10 m/s²

Formula:

`PE_(grav) = mass * g * height`

Solving:

`PE_(grav) = mass * g * height`

`PE_(grav) = 1*10*5`

`\boxed{\boxed{PE_(grav) = 50\:J}}\end{array}}\qquad\checkmark`

I Hope this helps, greetings ... DexteR! =)

Answer 2

`\bold{Hello \:\: Friend}`


Given :-

=> mass = 1 kg
=> height = 5 m


Potential energy = m*g*h

→ 1*10*5



Potential energy = 50 J




Hope It helps you. ^_^
