Asked by Tom
Science and medicine. Find the time required for an object to fall to the ground from a building that is 1400 ft high.
using the formula : t = 1/4 radical (s)
t=1/4 radical 1400
t= 10 radical 14*1/4
t= 5 radical 14 /2
what are I doing wrong I am suppose to be getting minutes and seconds
Here is how you do it. Start with the equation for how far something falls in time t.
1400 ft = (1/2) g t^2
"g" is the acceleration of gravity, which is 32.2 ft/s^2
t^2 = 2800/g = 86.7 s^2
t = sqrt 86.7 = 9.3 seconds
can you explain to me how you got the 2800 /g I got lost there
