160 it or - 50 m HE Figure 1 The Arc de Triomphe de l'Etoile is approximately 50.0 m tall One-dimensional motion describes the changes in the position of an object over time in terms of its displacement, velocity, and acceleration in one direction. The motion in that direction is independent of the displacement, velocity, and acceleration associated with any of the perpendicular directions. For example, the acceleration due to gravity near the surface of the earth has a value of 9.8 m/s', downward. This affects the vertical motion of an object but has no effect on the motion of the object in either of the horizontal directions. Thus, one-dimensional motion forms the foundation of our understanding of general motion in three dimensions. Instructions for this activity: For our discussion, you will address one of three slightly different versions of the case of a ball falling to the base of a 50.0 m tall building. Neglect air resistance. The magnitude of the acceleration is 9.80 m/s2. The eventual position of the ball is at the base of the building. 50.0 m below this initial position. Upward is defined as positive. Displacements, velocities, and accelerations directed upwards are positive. Conversely, if directed downwards, these same quantities are negative. Thus, the base of the building is located at -50.0 m, and acceleration is -9.80 m/s'. For the Case you are assigned, answer the following questions. Support your answer with any necessary calculations. How long does the ball take to reach the base of the building? What is the final velocity of the ball just before striking the ground? Answer the additional questions for your Case as specified in the table below. You will be assigned to your case study based on the table below:Freefall Case 3: Near the edge of the building the ball falls from rest to the base of the building. The words, "from rest" mean that the initial velocity 0.00 m/s. Additional question: Comment on the similarity or differences in the final velocity (just before striking the ground) between this case study and either of the previous two case studies. You may wait on posting a response to the additional question until results from cases 1 and 2 are available.To earn the maximum number of points for this discussion, you must: .
