Sheldon and Penny are sitting in the back seat of a car that is moving in the x-direction with avelocity of 20 m/s. Sheldon makes a snide remark and Penny responds by throwing the cap ofher soda bottle at him with a velocity of 11 m/s (in what we'll call the y-direction) in theirreference frame. From the point of view of someone standing alongside the road, the speed ofthat cap would be closest to:

Complete Question

The complete question is shown on the first uploaded image

The correct option is E

Explanation:

From the question we are told that

The velocity in the x direction is  

The velocity of the cap of the soda bottle in the y direction is  

  Gnerally the speed of the cap as seen by the observer  is mathematically represented as

=>    

=>    

=>    

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
