Problem 1 A small object is launched from the flat horizontal surface at an angle a = 60.0 with horizon. At that moment, ascending Sun is seen at an angle = 30.0 as shown in the picture below lg Determine velocity u of the object's shadow along horizontal surface after time T 1.0 s since the launching = = For calculations use acceleration due to gravity as g = 9.8 m/s. Initial velocity of the object is equal to vo 10.0 m/s. Friction forces with air can be neglected
