Question

A stone of mass 12 kg kept at a height of 15m will pose a potential energy equal to

Answer 1

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

Given

Mass of stone (m) = 12 kg

Height (h) = 15 m

======================================

To Find

Potential Energy

=====================================

Solution

Take Gravitational force (g) as 9.8 m/s²

We have formula :-

$\Huge{\boxed{\boxed{\sf{P.E \: = \: mgh}}}}$

___________[Put Values]

→ P.E = (12)(15)(9.8)

→ P.E = 180 × 9.8

→ P.E = 1764

$\huge{\boxed{\boxed{\sf{P.E \: = \: 1764 \: J}}}}$

∴ Kinetic energy is 1764 J
