A 4.0 kg block (m1) on a rough tabletop is attached by a string to a hanging block (m2) of mass 3.0 kg through a frictionless pulley. What is the frictional force on the mass m1 such that the hanging mass m2 is motionless?

A box of mass m1 rests on a smooth, horizontal floor next to a box of mass m2. suppose the force of 20.0 N pushes on two boxes of unknown mass.

A 2.00-kg block is placed on top of a 5.00-kg block. The coefficient of kinetic friction between the 5.00-kg block and the surface is 0.200. A horizontal force F is annlied to the 5.00-kg block. m g=9.8 (a) Draw FBD for each block. (b) Find force F that makes both blocks moving to the right with a = 3.0 m/s² 2.00 kg 2 (C) Find the coefficient of static friction between both blocks that prevents the 2.00-kg block to slide down when both blocks is moving with a = 3.0 m/s² 5.00 kg S F

Two objects with masses of 3.00 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley. Determine…  a) the accelertaion of each object  b) the tension in the string c) if the mass of the 3.0 kg object is increased to 5.0 kg – what is the tension in the string?
