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.
Velocity can be negative.
Speed cannot be negative.
A Scalar quantity has Only Magnitude, which is always a positive number and can Never be
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.
