A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?
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.

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
Coasting due West on your bicycle at 9.6 m/s, you encounter a sandy patch of road 6.7m across. When you leave the sandy patch your speed has been reduced by 3.8m/s to 5.8 m/s. a. Assuming the sand causes a constant acceleration, what was the bicycle’s acceleration in the sandy patch? Give both the magnitude and direction. b. How long did it take to cross the sandy patch? c. Suppose you enter the sandy patch with a speed of only 7.6 m/s. Is your final speed in this case 3.4m/s, more than 3.4m/s, or less than 3.4 m/s? Explain.

Caravan Analogy.Consider a highway that has tollbooths every 120 km. Suppose that cars travel at a rate of 120 km/hr (cars have instant acceleration to 120 km/hr and maintain that constant speed between tollbooths). If there is a convoy of 22 cars, and it takes each car an average of 24 seconds to clear the tollbooth, calculate the following. a. Suppose the caravan travels 360 km, beginning in front of one tollbooth, passing through a second and third tollbooth and finishing just after a fourth tollbooth. What is the end-to-end delay, in minutes, from the time the first car goes through tollbooth 1 until the last cargoes through tollbooth 4? b.The cast members of “The Fast and the Furious” show up. Instead of 22 cars, there arenow 18 cars. These 18 cars travel 220 km/hr instead of 120 km/hr. What is the new end-to-end delay in minutes? c. Consider the diagram below. The police are on to the cast of “The Fast and the Furious”. These 18 cars travel 280 km/hr on segments A and B (where…
