Question

find the potential energy of a body of 20 kg raised to a height of 6.2 m​

Answer 1

Answer:

Analysis→

Here we're given a body of mass 20kg which is raised to a height of 6.2m. And we've to find the Potential Energy(P.E) of the body at that height. And we know that the Potential Energy of a body is the product of its mass, g(acceleration due to gravity) and the height to which it's taken. (Assuming g= 10m/s²)

Given→

• Mass of the body= 20kg
• Height taken= 6.2m
• Acceleration due to gravity(g)= 10m/s

To Find→

Potential Energy of the body.

Answer→

$\Large{\underline{\boxed{\leadsto{\rm{P.E=mgh}}}}}$

$\rm\rightarrow{P.E=mgh}$

$\rm\rightarrow{P.E=(20kg)(10m/s²)(6.2m)}$

$\rm\rightarrow{P.E=20kg\times10m/s²\times6.2m}$

$\rm\rightarrow{P.E=20\times62\;joules}$

$\rm\rightarrow{P.E=1240joules}$

${\boxed{\boxed{\rightarrow{\rm{P.E=1240J\checkmark}}}}}$

☞ Hence the Potential Energy of the body at an height of 6.2m is 1240joules which is the required answer.
