Question 5.
A two-block system where Block A (4 kg) is on top of Block B (6 kg). Block A is pulled to the right with a 20 N force while friction between Block B and the ground is 10 N. Calculate the acceleration of both blocks and the tension in the string connecting them.
Show hintHide hint
Start with the total forces acting on the system.
Question 6.
In a pulley system, Block C (10 kg) is hanging and Block D (5 kg) is on a flat surface. Given the coefficient of friction between Block D and the surface is 0.2, find the maximum force that can be applied to Block D before Block C begins to descend.
