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 for 250 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 down until 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 then stops 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/min for 2.5 minutes. Almost home, she decelerates for the next 10 minutes until she reaches her house.

One of the most difficult things to learn in physics is that our everyday language is not always precise enough. For instance, we might say a car is “slowing down”, but that only gives us information abouts velocity, not its acceleration. What can we say about the velocity of a car which has negative acceleration in the x-direction? a. It is slowing down. b. The x-component of its velocity is decreasing. c. The x-component of its velocity is negative. d. It is speeding up. e. The x-component of its velocity is positive. f. The x-component of its velocity is increasing.
