Hello Forum,
Given position and related time data, what is the most correct way to calculate the instantaneous speed? For example, given the data (x1, t1) , (x2, t2), (x3, t3) , (x4, t4), (x5, t5), is the instantaneous speed at time t3 given more correctly by
[tex] v(t_3) = \frac{(x_4-x_2)} {(t_4-t_2)} [/tex]
[tex] v(t_3) = \frac {(x3-x2) } {(t3-t2)} [/tex]
[tex] v(t_3) = \frac {(x4-x3)} {(t4-t3)} [/tex]
and why?
Thanks!
