Question

Does anyone know this stuff? I’m so confused already

Answer 1

Answer:

see below

Explanation:

This graph shows an object initially travels at a constant velocity for 4 seconds.....the velocity is the slope of the graph for these 4 seconds.  

   then it remains stationary from t = 4 to t =6  ...see the graph is flat (slope = 0   means no velocity) ...at position 3  

  at t = 6 it reverses course ....a negative velocity (steeper slope ...higher velocity)  until it reaches position 0 at t = 9  

These times are what I think I can see...the graph is kind of fuzzy.

Answer 2

Explanation:

A position versus time graph gives the position of an object at a certain point in time. The slope, also known as the derivative, will give the change in the position with respect to time. The slope will give you the instantaneous velocity of the object due to velocity being defined as the change in position over time
