The problem of motion of a rigid body in an elastic medium is solved analitically for the case when a separation region caused by asymmetry is formed in front of the body. A scheme of flow around wedge-shaped and ogive-shaped bodies is given for the entire range of the velocities under consideration. It is shown that there exists a limit velocity such that the separation region disappears when the body moves at a velocity greater than the velocity of transverse waves. The forces exerted on a wedge-shaped body and on an ogive-shaped body are the same in the case of the limit velocity.
