Answer 1

hola!

Here,

→ Mass, m = 200 kg
→ Acceleration due to gravity, g = 9.8 m/s²
→ Potential Energy, P.E. = 9,800 Joules

P.E. = m × g × h

9800 = 200 × 9.8 × h

h = $\frac{9800}{200 \: \times \: 9.8} \: m$ = 5 m

Hence,
It should be raised upto the height of 5 metres (m)

Hope it helps! :)

Answer 2

Answer:

Step-by-step explanation:

Given :-

Mass of the bag = 200 kg  

Potential energy = 9800 J  

Gravity = 9.8 m/s²

To Find :-

Height = ??

Formula to be used :-

Potential energy = mgh

Solution :-

Potential energy = mgh

9800 = 200 x h x 9.8

h = 9800 / 200 x 9.8

h = 5 m

Hence, the height should it be raised 5 m.
