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

100 m

Explanation:

distance = speed x time

20×5 =100 m
