Macmillan Learning A runner is training for an upcoming race. In order to track the pace of the run, the runner is able to record time splits for the entire period. This allows the runner to produce the given velocity versus time graph. The run is broken into six segments. Assume the run is in a straight line. Answer the questions concerning this graph. Velocity (m/s) 5.00- 4.75- 4.50 4.25 4.00- 3.75- 3.50- 3.25- 3.00- 2.75- 2.50- 2.25 2.00 negative. zero. flat. 2 The average acceleration of the runner during segment 1 is positive. 3 دیا 5 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110 Time (s) 6

Figure below is a velocity-versus-time graph for a moving object. The object starts at position x = 0. What is the acceleration at t= 1.0 s, in m/s2? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. time in seconds

5. Draw a distance vs. time graph for Melinda’s journey. Her home is located at 0 meters.Melinda is riding her bike over to her friend Sara’s house to complete an assignment. Her friend lives 5 km away. She accelerates away from her home for250 m in the next 2.5 minutes. She then rides at a constant speed of 300 m/min for 15 minutes. Melinda sees Sara’s house approaching so she slows downuntil she reaches her destination in the next 2.5 minutes. She stays at Sara’s house for 30 minutes while they work on the assignment. It is time to go home,Melinda rides home at a steady speed of 250 m/min for 10 minutes. Melinda is getting tired so she slows down for 250 m during the next 5 minutes thenstops for 2.5 minutes to have a drink. Realizing it’s getting late, she had to speed up 1 km in the next 5 minutes then rides at a constant speed of 300 m/minfor 2.5 minutes. Almost home, she decelerates for the next 10 minutes until she reaches her house.

The goal of this lab is to draw conclusions about motion graphs and practice graphing motion. mtroduction: Motion graphs are important to understand how objects are moving. In this lab activity, we will create motion graphs from motion diagrams and from description situations. O8 ) = 1 s こ=} as 9 =1 8. Feet 4. 12 FIGURE 1-9 Motion diagram of a skateboarder, showing position and time. Part 1: Motion Diagrams Basics Instead of graphing from a data table, we will be graphing from a motion diagram. The diagram below shows Harold running from 0m to 100m on the track. He is moving along the positions, shown on the number line and his time at each position is tracked above him. Using these values, first create a data table. Then graph the motion (using time on the x and position on the y). Lor on Ceu 0 10 20 30 40 50 60 70 80 90 100 0 10 S0

figure 1 shows a velocity-versus-time graph for the bicycle trips of two friends with respect to the parking lot where they started. Xena's position at time zero is 0 and Gabriele's position is 60 m. Determine the displacement of Xena in 40 s.   Determine the displacement of Gabriele in 30 s.   What time interval is needed for Xena to catch Gabriele?

an object falls from rest on a high tower and takes 5.0s to hit the ground. calculate the objects position from the top of the tower at 1.0s intervals. Please make a position- time graph for the objects motion. Please make sure to include the equation that you used, a table of data, and the graph.

A roly-poly bug moves on the x axis. The bug has a variable velocity which is denoted by 2 v = t² - 2.50t.t is time in seconds and v is meters per second. The origin of the roly-poly bug is at t=0. Your job is to figure out the following after 3s have passed. Be sure to use the correct amount of sig figs! a) Velocity of the bug b) The bugs acceleration c) The bugs position THIS IS How I ROLL

The motion of a person as seen by another person is described by the equation v=-3.0m/s+0.5m/s^2t. Draw a motion diagram. draw a motion potion vs time graph draw a motion velocity versus time graph draw a acceleration vs time graph say everything you can about this motion and what happens to the person when his speed becomes zero.

Which of the following statements are true regarding velocity-time graphs?I.     The slope of a velocity-time graph is acceleration.     II.    The graph has a slope of zero if the object is at rest.     III.  A line with negative slope indicates that the object is slowing down.
