The table shows the position of a cyclist.

Question

t (seconds) 0 1 2 3 4 5
s (meters) 0 1.6 4.6 10.4 17.8 25.2

(a) Find the average velocity for the time period [1, 3].
? m/s

(b) Find the average velocity for the time period [2, 3].
? m/s

(c) Find the average velocity for the time period [3, 5].
? m/s

(d) Find the average velocity for the time period [3, 4].
? m/s

Help! I have no idea where to start with this question!

Answer 1

Do them all the same way.
It would e easier to see if the numbers in your table lined up one above the other.
The average velocity between time 1 (t1) and time 2 (t2) is:
(position2 - position1)/(t2 - t1)

The first answer is
(10.4 - 1.6)/(3 -1) = 3.25 m/s

Answer 2

Thank you! I was trying to make it harder than it really was! lol! Thank you again!

how do i find the instaneous velocity at t=
