Question

A man of mass 40 kg is in air find the potential energy of man at a height 20 m​

Answer 1

$\huge{\mathfrak{Ello!♡}}$

Given:-

•mass (m)= 40 kg

•height (h)= 20 m

•acceleration due to gravity (g)= 9.8 m/s²

To Find:-

Potential energy =??

Solution:-

As we know potential energy= m×g×h

putting the values;

$\huge \leadsto{ \tt{ \: 40 \times 9.8 \times 196}} \\ \\ \huge\leadsto{ \tt{ \: 40 \times 196}} \\ \\ \huge\leadsto \: { \boxed{ \bf{7840}}}$

•°• The potential energy of the man is 7840 Joules.

Answer 2

Given

Mass : 40kg

Height : 20m

Acceleration due to gravity :9.8

Potential energy :mgh

40 * 9.8 * 20

40 *196

7840

So ur answer is 7840

Hope it helps u♥♥
