Answer : The mechanical energy it possess is, 3.92 J
Solution : Given,
Mass of ball = 0.2 Kg
Height of object raised = 2 m
When an object falls then the formula used as,
[tex]w=mgh[/tex]
where,
w = work done
m = mass of an object
h = height of object raised
g = acceleration due to gravity = [tex]9.8m/s^2[/tex]
Now put all the given values in this formula, we get
[tex]w=(0.2Kg)\times (9.8m/s^2)\times (2m)=3.92J[/tex]
Therefore, the mechanical energy it possess is, 3.92 J
