If a 0.200-kilogram ball sits on a shelf 2.00 meters from the floor, how much mechanical energy (me) does it possess?

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,

where,

w = work done

m = mass of an object

h = height of object raised

g = acceleration due to gravity =

Now put all the given values in this formula, we get

Therefore, the mechanical energy it possess is, 3.92 J

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
