Answer:Given,
Work done by a engine (W) = 100 joule.
Mass (m) = 200g ↪ 0.2 kg
Acceleration due to gravity (g) = 9.8 m/s²
To Find,
How high it can be lifted.
According to the question,
According to work - Energy theorem,
Work done by a engine = Increase in potential energy.
[ Put the values ]
↪ W = m × g × h
↪ 100 = 0.2 × 9.8 × h
↪ 100 = 1.96 × h
↪ h = 100/1.96
↪ h = 51 m
Therefore,
The 51 m high it can be lifted
