A car is coasting backward downhill at a accelerate of 3.0 m/s when the driver gets the locomotive started. If uphill is chosen as the positive direction, what is the cable car ’ south average acceleration ? solution :ģ Practice Problems, Review, and Assessment Chapter 2 b. After 2.5 sulfur, the car is moving uphill at 4.5 m/s. A car is coasting backward downhill at a speed of 3.0 m/s when the driver gets the engine started.
If the bus took twice equally long to stop, how would the acceleration compare with what you found in share a ? solution : a.Ģ b. What is the average acceleration of the bus while braking ? b.
A bus is moving west at 25 m/s when the driver steps on the brakes and brings the bus to a barricade in 3.0 s. What is its average acceleration ? solution :ħ. The subspecies car in the previous trouble slows from 36 m/s to 15 m/s over 3.0 s. What is its median acceleration ? solution :Ħ. A race car ’ s forward speed increases from 4.0 m/s to 36 m/s over a 4.0-s time time interval. It accelerates upward for 2.0 s at a pace of 0.5 m/s, continues up at a ceaseless 2 speed of 1.0 m/s for 12.0 s, and then slows down with a constant downward acceleration of 0.25 m/s for 4.0 sulfur as it reaches the third floor.

View Notes.Īnd finally, we now offer a short 5-minute video tailored to the Concept Builder.Chapter 3 Practice Problems, Review, and Assessment SOLUTION: 2. Technical information, teaching suggestions, and related resources that complement this Concept Builder are provided on the Notes page. Learners and Instructors may also be interested in viewing the accompanying Notes page. However, the 18 different groups of questions can be printed. There is no need for an activity sheet for this Concept Builder. Users are encouraged to open the Concept Builder and explore. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress. The It's About Time activity provides a speed value at a given time of the trajectory and challenges students to determine the time at which two other speeds would exist. Question-specific help is provided for each question. The Speedometer activity challenges students to identify the location that an object would have a specified speed if given the initial launch speed.

The Describing Free Fall activity focuses student attention on what changes (if any) in the values and direction of the velocity and acceleration vectors are occurring over the course of the trajectory. There are three activities in the Concept Builder. The Free Fall Concept Builder is a concept-building tool that provides the learner with multiple practice modes for understanding the conceptual and mathematical nature of the velocity and acceleration of a free-falling object.
