The package has a weight of 5 lb and slides down the chute. When it reaches the curved portion AB, it is traveling at 8 ft>s (u = 0). If the chute is smooth, determine the speed of the package when it reaches the intermediate point C (u = 30) and when it reaches the horizontal plane (u = 45). Also, find the normal force on the package at C.
