If s is a position function, determine what s(5)-s(4) represents.
a) Instantaneous Velocity at t= 5 s
b) average velocity between t=4 s and t=5 s
c) Instantaneous velocity at t = 4 s
d) Position between t = 4 s and t = 5 s
I believe the answer is d.
Actually....I believe "b" is correct
Avg velocity = s(b) - s(a)
b - a
s(5) - s(4)
_________ = s(5) - s(4)
5 - 4
I thought it might be "b" but wouldn't they normally put it over a fraction? That's what made me think Position "d"
Because if we think about it slope is (Average velocity) is change in position / time traveled.
