Sum of velocity

Web12 Sep 2024 · Figure \(\PageIndex{1}\): (a) Velocity of the motorboat as a function of time. The motorboat decreases its velocity to zero in 6.3 s. At times greater than this, velocity becomes negative—meaning, the boat is reversing direction. (b) Position of the motorboat as a function of time. At t = 6.3 s, the velocity is zero and the boat has stopped. Web5 Mar 2024 · But the sum of two velocity vectors would not typically be a valid velocity vector at all, since it would not have unit magnitude. This lack of additivity would in any case have been expected because velocities don’t add linearly in relativity (section 3.3). ... That is, the velocity vectors are the observer-vectors \(o\) of chapter 1, but ...

This is a quick follow-up to the above section. If we were to vary v1 and v2 to find out the maximum and minimum values for the resultant velocity, then, on the basis of the results obtained above, we would get the lowest value when v1 = v2 = 0, and the highest value when v1 = v2 = c. So —
