IMG_20190307_110207.jpg Arrangement of two block system is
as shown in the figure . mass of block
A is
•m A 5K g
and mass of B is 10Kg
A constant force F = 100 N applied on
upper block A . Friction between A
and B is
and b/w B and ground
surface is smooth , then find work
done by frictional force on block B in t
= 2 sec if system starts from rest
smooth
