I am taking PHYS 103 Lab. I need help with the 2nd and 3rd bullet point assuming the building is 23 meters high.

Write the due date of this assignment: Month and Day (For example, July 15 would be Month = 7. Day = 15) For a building having a height equal to the quantity you have recorded for Day in meters (in our example 15 meters), compute the time required for the ball to fall to the ground while experiencing acceleration due to gravity (g=9.8m/s2). How fast was the ball traveling when it hit the ground
