An object with a mass of #10 kg# is on a plane with an incline of # - pi/4 #. If it takes #12 N# to start pushing the object down the plane and #7 N# to keep pushing it, what are the coefficients of static and kinetic friction?
The mass of 10Kg on the incliine resolves to a 98N force vertically.
The component along the plane will be :
Let the static friction be
Static Friction force =
Let kinetic friction be
Kinetic Friction force =
