Stuart left his house at noon and walked north on Pine Street for minutes. At that point he realized he was late for an appointment at the dentist, whose office was located south of Stuart’s house on Pine Street; fearing he would be late, Stuart sprinted south on Pine Street, past his house, and on to the dentist’s office. When he got there, he found the office closed for lunch; he was minutes early for his appointment. Stuart waited at the office for minutes and then found out that his appointment was actually for the next day, so he walked back to his house. Sketch a graph that describes Stuart’s position over time. Then sketch a graph that describes Stuart’s velocity over time.
Graph of the position of person S is given below:
Graph of the velocity function overtime is given below:
According to the given situation Sketch graph
1 > graph position over time
2 > graph velocity over time
The position of the person S at time is . As the time increases the person S moves towards north for minutes.
Consider the north direction indicates the position axis.
After minutes, the person moves towards the south which is indicated by the negative direction.
Person S moves minutes towards the south and rested for minutes then moves towards the north.
Consider the person S moves towards the north with the constant with for minutes. The speed in the direction of north is positive and the speed of person S in the direction of the south is negative.
Person S runs for minutes with constant speed then runs minutes in the direction of south which is considered as negative.
Graph the velocity function over time with the help of the above description.
