Explanation:
Patent law in the US is the Patent Act. It protects new inventions and establishes the US Patent Office to accept patent applications. Its authority is from the US Constitution which says "Congress shall have power to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries."
Explanation:
Velocity is a vector quantity. Velocity = speed +direction.
In this problem, we can say that any time during their trip their velocity was -20 m/s. It is due to the above reason that the velocity is a vector.
When the displacement of the object is negative, the average velocity will be negative.
For example, when an object moves in the negative direction, it will have negative velocity.
