USE VELOCITY FORMULA FOR THIS ACTIVITY.

Reflection Direction: Write a reflection on the uniform accelerated motion by answering the question inside the box. You may write your answer in a more critical and creative presentation of your learning. What concepts and skills did you learn in this module and how can you apply it in real life situations? Can you cite something you have learned from the past that is connected to the concepts/skills you learned in this module? What concepts, information, skills would you like more time practicing or working to better understand? Post-Test Directions: Read the questions carefully. Write the letter of the correct answer on the blank provided before the number. 1. Which of the following in statements describe acceleration operationally?. A. distance over time B. displacement over time C. change in position over time D. change in velocity over time 2. Which of the following statements is a CORRECT interpretation of the velocity va. time graph below? A. The body is at rest B. The body is moving at a constant velocity. C. The body is moving towards positive direction with uniform acceleration. D. The body is moving towards negative direction with uniform acceleration. 8 3. The position vs. time graphs below illustrate the motion of an object with uniform acceleration. Which graph corresponds to a motion towards negative direction with increasing velocity? K"DZ" 4. A police car is traveling at a constant speed of 8.0 m/s when the driver pushes the gas pedal resulting for the car to accelerate at a constant rate of 2.5 m/a2. What will be the new speed of the car after 4.0 seconds? A. 10.0 m/a B, 15.0 m/a C. 18.0 m/s D. 20.0 m/s 5. The take-off speed Boeing 757 is 260 km/h (about 72 m/s) and can maintain an acceleration of 1.08 m/s3. If the plane accelerates from rest, how long should the runway be for it to reach the take-off speed? A. 1 600 m B, 2 000 m C. 2.400 m D. 2 800 mCheck Your Understanding A car accelerates uniformly from rest at a rate of 3 m/s' for 4 seconds. Then it moves at a constant velocity for 5 seconds. Finally, It slows down uniformly at a rate of -4 m/s until it comes to a stop after 3 seconds. & = 9'm/sa &=24 m/s -= A. Fill out the table with information about the velocity of the car.
