WebThe kinetic frictional force between the 1 kg block and the inclined plane is 4 N while the frictional force between the 2 kg block and the inclined plane is 8 N. 3.1.1 Draw a labelled free-body diagram showing All forces acting on the (5) 1 kg block. 3.1.2 Calculate the magnitude of the tension in the string connecting the (5). WebFrictional force is defined as frictional coefficient x normal force. In this instance normal force is equal and opposite to Gravitational force which is equal to mass x gravity constant. So if you substitute all of this in you are left with two equations, assuming frictional force is equal to the total force. a=Ff/m.
