5. Groups of physics students are each given a force scale (to measure an applied
force of magnitude Fa), an electronic balance (to measure the mass, m), a rectangular
wooden block with a hook at one end, a protractor, and a piece of string. Each group
must determine the force of kinetic friction acting on the block as it is pulled with a
constant velocity along a horizontal lab bench. However, the applied force must be at an
angle 0 above the horizontal.
(a) Draw a system diagram and an FBD of the block for this investigation.
(b) Derive an equation for the magnitude of the normal force on the block in terms of
the given parameters Fa, g, m, and 0.
(c) Derive an equation for the magnitude of friction on the block in terms of Fa and 0.
