From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!

Change in Position Exercises

Example 1

Let s(t) be a position function with velocity function v(t) = s'(t).

(a) If s(9) = 4 and , what is s(12)?

(b) If s(3) = -2 and , what is s(5)?

Example 2

A koala is climbing up and down its tree with velocity v(t) feet per minute, where positive values of v(t) indicate the koala is climbing up the tree.

At t = 0 minutes the koala is 5 feet above ground.

(a) If  feet, how high is the koala after t = 4 minutes?

(b) If  feet, how high is the koala at t = 7 minutes (use part (a))?

Example 3

A hummingbird flies away from its feeder with velocity v(t) feet per second and position s(t) feet away from its feeder.

(a) If s(4) = 5 feet and  feet, find the hummingbird's distance from the feeder at time t = 0.

(b) If s(10) = 16 feet and  feet, find s(5).

Example 4

Let s(t) be a position function with velocity function v(t) = s'(t).

(a) If  and s(9) = -3, what is s(8)?

(b) If  and s(7) = -4, what is s(3)?

(c) Given (a) and (b), what is ?

(d) Given (a) and (b), what is ?

Example 5

Let s(t) be a position function with velocity function v(t) = s'(t).

(a) If s(2) = 7 and s(9) = 13, what is ?

(b) If s(2) = 13 and s(9) = 7, what is ?

(c) If s(2) = 13 and s(9) = 7 then what is ? (hint: one of the properties of integrals says how to change the limits of integration)
