horrorfan [7]

Answer:

Part a)

$W = 2716.5 J$

Part B)

$W = -2716.5 J$

Explanation:

Part A)

While escalator is moving up work done to move the person upwards is given as

$W = mgh$

here we know that

m = 63 kg

h = 4.4 m

now we have

$W = 63 \times 9.8 \times 4.4$

$W = 2716.5 J$

Part B)

Work done while we move from up to down

So we have

$W = - mgh$

so we have

$W = -2716.5 J$
