Two objects A and B are moving on rough surface as shown in figure. If object A has greater speed than B then?

?

Select one:

a.?A experiences more frictional force than B

b.?B experiences more frictional force than A

c.?Both experience same frictional force

d.?Cannot be said because data is insufficient.

Dear student ,
Answer is option B 
that B will experience more frictional force , as frictional force do not depend on the speed , it depends on the mass.
as 
friction = uN 
and N= mg
