The problem of motion of a rigid body in a medium is solved analytically with consideration of dry friction. The effect of contour geometry, friction, and velocity on the drag force is studied for bodies of two contour geometries. It is shown that a body with a convex contour experiences the least drag, since the medium is separated from the body surface at the early stages of motion. The effect of friction and velocity on the size of the contact region is also studied.
