Question

The string passes over a frictionless pulley. The coefficients of static and kinetic friction
are 0,40 and 0.28 respectively. When the system of masses is released, block A slides
across the table
1.1 Define a frictional force.
1.2 Calculate the magnitude of the maximum static frictional force acting on block A (2)
1.3 Calculate the force of kinetic friction acting on the 3 kg block.
1.4 Draw a fully labelled free-body diagram for each block.
(6)
7.5 State Newton's second law.
(3)
1.6 Calculate the acceleration of the system of blocks and the magnitude of the tension
T in the string​
