A body of mass 20 kg is resting on a table. A light string is attached to it and passed over a smooth pulley at the edge of the table and a mass 3kg is attached at the free end. What is the acceleration of the system of the coefficient of kinetic friction between the massand the table is 0.04 ? What is the tension in the string ?

1.	A body of mass 20 kg is resting on a table. A light string is attached to it and passed over a smooth pulley at the edge of the table and a mass 3kg is attached at the free end. What is the acceleration of the system of the coefficient of kinetic friction between the massand the table is 0.04 ? What is the tension in the string ?
Answer» SOLUTION :`a=(m_(1)G-mu_(K)m_(2)g)//m_(1)+m_(2)=3xx9.8-0.04xx20xx9.8//23=0.94ms^(-1)`. `T=m_(1)(g-a)=26.58N`
