This position time graph describes an object's motion. Use it to predict the position (in m) of the object at a time of 24.0 seconds.

A physics teacher walks 5 km East, 2.5 km South, 5 km West, and finally 2.5 km North. The entire motion lasted for 3 hours. Determine the average speed and the average velocity.

An Australian magpie (Gymnorhina tibicen) flies 53 m south and then 47 m west, in a total time of 35 minutes. What is its displacement from the starting position? Enter only the numerical part of your answer (in m) to the nearest integer.

Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.26 m/s, due west. This average velocity results, because she hikes for 6.62 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.381 m/s due east. How far east did she walk (in kilometers)? dw VE West East dɛ Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work

1) You recorded your position with respect to the front door of your house as you walked to the mailbox. Examine the data presented in the table provided in the book and answer the following questions:   (a) What instruments might have you used to collect data?   (b) Represent your motion using a position-versus-time graph.   (c) Tell the story of your motion in words.   (d) Show on the graph the displacement, distance, and path length.

Two kids are racing towards a toy somewhere between them. Albert has 3.90 times further to run than Betty. Albert is to the West of the toy and Betty is to the East of the toy. Albert runs at a constant speed of 1.60 m/s. It takes him 2.90 s to reach the toy.How far did Albert run to reach the toy?

(a) Calculate the height (in m) of a cliff if it takes 2.30 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.07 m/s. (Enter a number.) m (b) How long (in s) would it take to reach the ground if it is thrown straight down with the same speed? (Enter a number.) s †

An airplane flies eastward and always accelerates at a constant rate. At one position along its path, it has a velocity of 34.9 m/s . It then flies a further distance of 49300 m , and afterwards, its velocity is 42.7 m/s . Find the airplane's acceleration. acceleration: Calculate how much time elapses while the airplane covers those 49300 m. elapsed time:

Some experimental researcher tells us that the position of an object as a function of time is given by x(t) = at3 - bt2 + ct - d, where the constants are a = 3.6 m/s3, b = 4.0 m/s2, c = 60 m/s and d = 7.0 m. Find the average acceleration over the first 2.4 seconds. A) 18 m/s/s B) 54 m/s/s C)36 m/s/s D) 76 m/s/s

For the following function models the position s(t)s(t) of an object moving along a stright line, where tt is in seconds and ss is in meters. s(t)=t2-6t Find the simplified expression for the average velocity from t=7t=7 to t=7+ht=7+h. s(t+h)-s(t)/h=?
