An overinflated basketball initially at rest explodes into three parts, shown below. The part that travels at 12 m/s is flying perfectly northward, and the part that has a speed of 16 m/s is traveling perfectly east. Assume all parts have an equal mass of about 0.25 kg. Overhead view: 12 m/s 16 m/s North a) Your friend in class makes the following statement about this situation: "The unknown velocity, v, must equal 28 m/s, because that way the part of the soccer ball that's headed in that direction will balance out the velocities of the other two combined." Thoroughly assess and, if necessary, correct your friend's reasoning in a clear, coherent paragraph, which may be supported by equations and/or diagrams. b) The velocity, v, is not perfectly southwest. What exact direction is it? Give an angle, and specify the direction to which that angle is relative. An overinflated basketball initially at rest explodes into three parts, shown below.
