Use matlab to plot the three types of damping (force vs velocity). show your plots on a single page. a) coulomb damping (friction) for 3kg 3kg block sliding on a surface with a coefficient of friction, n 0 3. b) viscous damping, c n mm s 3 / ( / ). c) aerodynamic damping in air at sea level. the block has a frontal area of m2 1 and a drag coefficient of 0 29 .

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
