Interpreting "O" as zero displacement, the initial position of the car at the chosen reference frame's origin is 0 meters. This signifies that the car commences its motion from the reference frame's origin at time t = 0, with no initial displacement recorded.
The position-time data "4 s(m) 80 60 20 O 10 20 50 t(s)" suggests the car's positions at different time intervals. Considering the reference frame at the origin, the notation "O" at 20 seconds indicates the position of the car at that moment. In this context, "O" likely represents zero displacement from the origin.
Therefore, the initial position of the car with respect to the chosen reference frame at the origin, when the time is denoted by "t(s)," is 0 meters.
This means that at the beginning of the observed time interval, the car is situated exactly at the reference frame's origin. The data implies no initial displacement, indicating that the car starts its motion from the reference frame's origin at time t = 0.
Complete question:
In the context of a car's motion described by the position-time data given as "4 s(m) 80 60 20 O 10 20 50 t(s)," considering the reference frame at the origin, the question can be formulated as follows: What is the initial position of the car with respect to the chosen reference frame when the time is denoted by "t(s)"?
