Sub: Physics Topic: Mechanics Question: Finding the velocity of the third piece while exploding an object into three pieces. ClassOf1 provides expert guidance to College, Graduate, and High school students on homework and assignment problems in Math, Sciences, Finance, Marketing, Statistics, Economics, Engineering, and many other subjects. An object at rest explodes into three pieces of equal masses. one moves east at 23 m/s, while the second piece moves northwest at 14 m/s. What is the velocity of the third piece? Assume each piece has a mass of 2 kg. Solution: Velocity can be negative. Speed cannot be negative. A Scalar quantity has Only Magnitude, which is always a positive number and can Never be negative. For instance, speed can Never be negative. A Vector quantity on the other hand has two components: Magnitude and Direction. Velocity is a Vector quantity. It tells us about the speed of the object and also, the direction in which it travels.
