The flatbed truck starts from rest on a road whose constant radius of curvature is 32 m and whose bank angle is 6°. if the constant forward acceleration of the truck is 3.5 m/sec2, determine the smallest time t after the start of motion at which the crate on the bed begins to slide. the coefficient of static friction between the crate and truck bed is ms = 1.1, and the truck motion occurs in a horizontal plane.
