HOLT PHYSICS Motion Life Dimensions Graph Skills Displacement and Velocity A minivan travels along a straight road. It initially starts moving toward the east. Below is the position-time graph of the minivan. Use the information in the graph to answer the questions. 15 + 10 + position (m) 5 tz 1.3 t4 for 0 10 20 30 40 50 60 70 .. time (s) -5 1. Does the minivan move to the east? If so, during which time interval(s)? 2. Does the minivan move to the west? If so, during which time interval(s)? 3. Is the minivan's speed between t and to greater than, less than, or equal to its speed between tz and to? 4. Is the minivan's speed between ty and to greater than, less than, or equal to its speed between to and ty? 5. Does the minivan ever stop completely? If so, at which time(s)? 6. Does the minivan ever move with a constant velocity? If so, at which time(s)? 7. What is the total displacement of the minivan during the trip? Motion in One Dimension IN
