Select all that apply. a 0.200-kilogram ball sits on a shelf 2.00 meters from the floor and then falls to a point 1.00 meter from the floor. ignoring any affects due to friction, at this position its mechanical energy is 3.92 jits potential energy is 3.92 jits kinetic energy is 3.92 jits potential energy is 1.96 jits kinetic energy is 1.96 jits mechanical energy is 1.96 j

Mechanical energy of the ball will remain conserved

so here we have

so mechanical energy will remain same at all positions

Now when ball comes to position of 1 m height then potential energy is given as

Now since total mechanical energy is conserved so we will say

so we have

its mechanical energy = 3.92 J

its potential energy = 1.96 J

its kinetic energy = 1.96 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.
