In the e below, the white ball travelling with a speed of 3.0 m/s strikes a black ball that is at 3 of 4 nd follows the path shown. The black ball has a speed of 1.5 m/s immediately after the on, 60 below the positive x-axis. 3.0 m/s O 60.0 1.5 m/s a. What is the speed and direction of the white ball after the collision? b. By using appropriate calculations, determine if the collision is elastic or inelastic. 10. The drawing shows a sulphur dioxide molecule. It consists of two oxygen atoms and a sulphur atom. A sulphur atom is twice as massive as an oxygen atom. Using this information and the data provided in the drawing, find (a) the x coordinate and (b) the y coordinate of the center of mass of the sulphur dioxide molecule. Express your answers in nanometers (1 nm = 10" m). Oxygen Oxygen 60.0 60.0 0.143 nm 0.143 nm Sulfur 11. A fireworks rocket is moving at a speed of 45.0 m/s. The rocket suddenly breaks into two pieces of equal mass, which fly off with velocities v, and v2, as shown in the drawing. What are the magnitudes of (a) vi and (b) vz? V1 30.09- 60.0 V2 45.0 m/s
