1. A block of mass 290 g is at rest on an architects drafting desk table top. The surface of the desk has the ability to be raised at a particular angle to make for ease of writing. Currently the desk inclined at an angle Ө = 10° as shown in the image below. The coefficient of static friction is 0.4 and the coefficient of kinetic friction is 0.25.
What is the frictional force acting on the box? Include all relevant visualizations and mathematical models.
