Question 3
Problem Statement: The mail carrier and a crazy dog begin traveling toward Ms. Calloway’s house 4:00 pm. The mail carrier starts 1200 meters East of the house and walks at 2 meters per second. crazy dog starts 3600 meters West of Ms. Calloway’s house and runs at 3 meters per second

3.1 Draw a picture in the space below to help your friend understand the problem without reading the problem statement.

Question 3.6
Draw a position versus time graph that shows the mail carrier’s trip toward Ms. Calloway’s house.


-1.2638581 14.514286
Question 3.7
Draw a position versus time graph that shows the mail carrier’s and the crazy dog’s trips toward Ms. Calloway’s house.








During which time segments do Jim and Ken move in the same direction? Check ALL that apply A B C D E Explain your answer
Some researchers are using motion sensing devices to study the motion patterns of wild animals. The devices provide graphs of an animal’s VELOCITY vs. time as it tracks its prey. The graph below shows a segment of an animal’s VELOCITY.





Which of the following describes the motion of the animal during segment D? Check ONLY one speeding up slowing down moving at constant speed not moving Explain your answer





New page content Which of the following describes the motion of the animal during segment C? Check only one speeding up slowing down moving at constant speed not moving Explain your answer
A car starts at point A and speeds up at a constant rate in the positive direction until it reaches point B in 3 seconds, where it suddenly stops. The car waits at point B for 3 seconds. It then travels at constant speed in the opposite direction, reaching point A again in another 3 seconds.


Sketch a POSITION-TIME graph of the motion during these 9 seconds.



Sketch a VELOCITY-TIME graph of the motion during these 9 seconds.


New Question





Are speed and velocity the same or different? (Choose one) same different Explain your answer. Give one example. Use complete sentences.
