Chapter 2 Test: Intro to Physics Written Portion (30pts + EC) Directions: This is the written portion of your Chapter 2 Test. Be sure to SHOW ALL YOUR WORK to receive full credit. Remember that showing your work is 60% of your grade, whereas having the right answer mumbewunitlabels) is only 40% VF a S 1. Rickiela just went out for a 45 minute bike ride. a. During her bike ride she traveled 3km West . Then, she turned North and traveled 2km. c. She turned again and went 5km East. d. Finally, she turned South and went another 5km. Plot the motion on this grid (3pts) What is Rickiela's total Distance? (3pts) What is her Displacement? (3pts) What is her Average Speed? (3pts) What is her Average Velocity? (3pts) 2. Levi is planning on meeting her friend at the park in 15 minutes. If she lives a distance of 5 km away from the park, what speed will she have to ride her bike at to get there in time? (5pts) 3. Jaydin is riding his bike at the park at a velocity of 7 m/s. He then starts going down a hill, which accelerates him at 10 m/s' for a total time of 4 seconds. What is Jaydin's final velocity at the bottom of the hill? (5 pts)The following Position vs Time graph shows someone's 20 minute running Slope X, - X workout on a Northbound trail. Use it to answer these last couple questions: 2000 4. What is the average velocity of the person between 4 minutes and 9 minutes 1800 into their run?
