✨pls answer✨​

Answer 1

$\large \bold{ \underline{ \underline{ \: Answer : \: \: \: }}}$

$\to$ Work done = 80000 Joule

$\large \bold{ \underline{ \underline{ \: Explanation : \: \: \: }}}$

$\to$ Mass ( m ) = 70 + 10 = 80 kg

$\to$ Height ( h ) = 100 m

$\large \fbox{ \bold{ \fbox{ \: \: Work \: done = mgh \: \: }}}$

$\to$ Work done = 80 × 10 × 100

{ Since , g = 10 m/s² }

$\to$ Work done = 80000 Joule

Answer 2

Answer:

80000 Joules will b the answer

Explanation:

Total mass = 70kg + 10kg

                  = 80 kg

Now , we know that :-

Work done = mgh

                   = 80kg * 10 m/s^2 * 100m (g = 10m/s^2)

                   = 80000 Joules

Hope u all understood the answer , THANK U !
