Answer:

Explanation:
Kinetic energy is given by the following equation:
, where
is mass in
and
is velocity in
.
Since the cell phone's mass is given in grams, we need to convert this into kilograms:
.
Therefore, the kinetic energy of the cell phone is:
.
The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces
(ii) roughness of the surface
(iii) deformation of bodies.
