Homework Statement
Mass m1=25.3 kg is on a horizontal surface, connected to mass m2= 5.10 kg by a light string as shown. The pulley has negligible mass and no friction. A force of 201.7 N acts on m1 at an angle of 30.9o.
The coefficient of kinetic friction between m1 and the surface is...
i tried it doesn't work, i have the same question but but different m
m1=2 m2=8 m3=4
i get zero for answer and its wrong... i did exactly the same way you did above...
