4. At the distribution center of a company that offers express delivery, shipping, and courier services, a series of large-sized packages, each with a mass of about 10 kg, are dispatched from a conveyor belt as shown below. The coefficient of static friction between the surface of the conveyor belt and each package is 0.8. Determine the angle 0, in degrees, where the packages first slip relative to the belt (loses contact with the conveyor belt). Assume that the package does not slip at any point, when it is still in contact with the conveyor belt. 0.35 m/s 1000 mm
