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/s².

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?

-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.
