The object moves in the positive x-direction until t = 3 s, and then the object is at rest C. The object's position is constant until ( = 3 s, and then the object begins to move in the positive x-direction D. The object moves in the positive x-direction from t = 0 to t # 3 s, and then moves in the negative x-direction from t = 3 s to f = 5 s 18. Carl Lewis got a world record for the 100.om run with a time of 9.86s.

Your discussion partner says both balls undergo the same acceleration. What will be your response? A. YES, because both balls decelerated at the same rate B. YES, because the acceleration due to gravity is constant for both cases C. NO, because they went downward on different directions D. NO, because the first travel twice the distance as the other ball 25. An aspirin is dropped from a certain height. Which of the following is true about the object as it moves down? A. The acceleration increases C. The speed decreases B. The speed stays the same D. The speed increases 26. A simple way of measuring a person's reaction time is to let the person catch a freely falling ruler or meter stick and then measure the distance from the point where the fingers of the person was placed before the ruler is released to the point where the person's finger was located after the ruler was released. If the distance of fall is 19cm, what is the person's reaction time? A. 19s B. 1.9s C. 0.2s D. 0.1sspeed of the falling Bust A and B dby continues in motion by its own inertia is called a 30.
