Explanation: 5 dunno
I salute those PWD who helped the country and I look up to them because they're an inspiration.
h = y = 1472 ft = 448.6656 m
g = -9.81 m/s/s
(*We will only be needing the positive value of the quadratic formula for the time.)
(a) How long would it take for an object be dropped from the building to reach the ground?
a = 4.905 ; b = 0 ; c = 448.665
t = 9.564050938 s
t = 9.56 s
(b) What would be the objects final velocity be?
(a) The time would take for an object be dropped from a 1472 ft building is 9.56 s; and (b) its final velocity is 307.69 ft/s.
