A grandfather is waiting for his grandchild, pacing back and forth in a straight line in a long narrow waiting room. Starting at a point in front of the door, he walks 12 paces east, then 5 paces west,the 4 paces east, then 8 paces west,then 2 paces east, then 10 paces west, when finally, after he has walked 3 more paces east and stopped. At that point, what distance has the grandfather covered? What is his total displacement? what is his average speed, if he paced for 5.0 minutes? what is his average velocity, if he paced for 5.0 minutes?

Two runners start simultaneously from the same point on a circular 200-m track and run in opposite directions. One runs at a constant speed of 6.20 m/s, and the other runs at a constant speed of 5.50 m/s. When they first meet, (a) for how long a time will they have been running, and (b) how far will each one have run along the track?
Suppose you went for a drive along a long, straight road that runs east-west. Let's define east to be the positive x direction. From your home, you drive east at 30. mi/hr to your friends house for 20. minutes, then at 48 mi/hr east for 10. minutes to the grocery store. Finally, you drive west at 60. mi/hr without stopping to get home. How many minutes will it take to drive from the grocery store to your home (at 60. mi/hr)? Note: Your answer should have the correct number of significant figures
You are exploring a planet and drop a small rock from the edge of a cliff. In coordinates where the +y direction is downward and neglecting air resistance, the vertical displacement of an object released from rest is given by y − y0 = 1/2gplanett2, where gplanet is the acceleration due to gravity on the planet. You measure t in seconds for several values of y − y0 in meters and plot your data with t2 on the vertical axis and y − y0 on the horizontal axis. Your data is fit closely by a straight line that has slope 0.300 s2/m. Based on your data, what is the value of gplanet?

An unidentified flying object (UFO) is observed to travel a total distance of 49000 m, starting and ending at rest, over a duration of 3.07 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2. 20,796 g s 10,398 g s 2,120 g s 1,060 g s
One day you go hiking at a nearby nature preserve. At first, you follow the straight, clearly marked trails. From your starting point, you travel 2.00 miles down the first trail. Then, you turn to your left by 30.0∘ to follow a second trail for 1.60 miles. Next, you turn to your right by 160∘ and follow a third trail for 2.00 miles. At this point, you are getting very tired and would like to get back as quickly as possible, but all of the available trails seem to lead you deeper into the woods. You would like to take a shortcut directly through the woods (ignoring the trails). How far should you walk, to go directly back to your starting point?
