Answer:
Work done, W = 98 J
Explanation:
It is given that,
Mass of the object, m = 5 kg
vertical distance covered by it, h = 2 m
To find,
Work done in lifting the object.
Solution,
The force needed to lift an object is equal in size to the gravitational force on the object. Let W is the work done to lift an object. It is given by :
[tex]W=F\times d[/tex]
F is the force acting on the object, F = mg
[tex]W=m\times g \times h[/tex]
[tex]W=5\times 9.8 \times 2[/tex]
W = 98 J
So, the work done by the object is 98 joules.
