Conveyor belt A, which forms a 20 angle with the horizontal, moves at a constant speed of 4 ft/s and is used to load an airplane. Knowing that a worker tosses duffel bag B with an initial velocity of 2.5 ft/s at an angle of 30 with the horizontal, determine the velocity of the bag relative to the belt as it lands on the belt. 1.5 ft (VB)0 B 30 20 The velocity of the bag relative to the belt as it lands on the belt is ft/s at an angle of
