Chris has two options for getting from school to his house. In this problem, we will model the entire trajectory as one-dimensional motion. The distance from school to Chris's house is 20.0km.
The first choice involves riding a bicycle at a constant velocity of 10 m/s avoiding any traffic.
The second choice involves driving a car taking the following steps: First he drives at a constant velocity at 8m/s for 6.0km. He then stops for 5 minutes due to a trafficjam. After the traffic jam, he drives another 4km at a constant velocity of 10m/s. He then accelerates at a constant rate from 10m/s to 20m/s over a distance of 5km. Lastly, he drives the remaining 5km at a constant velocity of 20m/s.
a) Determine total time it takes chris to reach his home from school if he rides his bicycle.
b) Determine the total time it takes chris to reach school if he drives his car.
c) Draw a graph of velocity vs time for the trip on the bicycle. Label the x and y axis and ensure numerical value provided are provided.
d)draw a graph of the velocity vs time for the trip home in the car. label x and y axis

From his house, Jack bikes at a constant velocity of 8.5 m/s {east} for 40 seconds. He suddenly stops and takes a 10 second break. Then he heads south at a constant acceleration of 1.3 m/s/s {south} for 7.0 seconds. Determine his average velocity for the entire trip
