An object falls from rest on a high tower and takes 5.0 s to hit the ground. Calculate the object’s position from the top of the tower at 1.0 s intervals. Make a position-time graph for the object’s motion. In your response, show what you are given, the equation that you used, any algebra required, a table of data, and your graph. g = 9.8 m/s 2 Answer: Given info ; Gravity = 9.8 m/s^2 / It took 5 seconds for the object to hit the ground / Unknown : How tall the building is Equation for falling motion : f(x) = 4.9(t^2) f(1) = 4.9*1 = 4.9 m f(2) = 4.9*4 = 19.6 m f(3) = 4.9*9 = 44.1 m f(4) = 4.9*16 = 78.4 m f(5) = 4.9*25 = 122.5 m Time (sec) Position from ground (m) 1 122.5 2 102.9 3 78.4 4 44.1 5 0 1 2 3 4 5 0 20 40 60 80 100 120 140 Position from ground (m) Score
