Problema Solution
how long would it take for a ball dropped from the top of a 144 foot building to hit the ground
Answer provided by our tutors
As an object falls, its speed increases because it’s being pulled on by gravity.
The acceleration of gravity near the earth is g = 32.2 feet/sec^2.
The formula for T = time of the fall is
T = (2d/g)^0.5
where d = 1440 foot and g = 32.2 feet/sec^2
T = (2*1440/32.2)^0.5
T = 9.457 sec approximately.
The ball will hit the ground in approximately 9.457 seconds.
