A block of mass 1.26kg is resting on an inclined surface that is tilted at 0=28.0°. (a) Draw the free body diagram for the block as it sits on the inclined surface. (3 pts - include your free-body diagram in the scanned/submitted work for grade.) स (b) What is the least value the coefficient of static friction between the block and the inclined surface? (10 pts - include your work and answer in the scanned/submitted work.) (c) Now you are pushing the block up the inclined surface with a force parallel to the surface, and the coefficients of static and kinetic friction between the block and the inclined surface are 0.322 and 0.180, respectively. Note that the frictional force behaves differently now, and the free body diagram does not look the same as in (a). Draw a revised free-body-diagram for (c) first. (3 pts - include in the scanned/submitted work) Find the force (in N) required to push the block at a constant speed. (10 pts - enter your answer below)
