Answer:
The time the object takes to fall on the ground from 224 feet is 3.74 s.
Step-by-step explanation:
In this case we have a known quantity, the distance of the fall that is 224 feet and a equation that represents the motion of this fall that is d = 16t^2. We wish to find the time it'll take this object to fall, so we can solve this equation for t. It goes as follows:
d = 16t^2
d/16 = t^2
t^2 = d/16
t = \sqrt(d/16)
t = [\sqrt(d)]/4 = [\sqrt(224)]/4 = 14.97/4 = 3.74 s
where \sqrt is the square root of the number.
Answer:
3.7 seconds
Step-by-step explanation:
We were provided with the equation d=16t² so as to determine the time t in seconds it takes for an object dropped to fall a distance of d-feet.
The question says how long(in seconds does)it take for a fall of 224 feet.
16t²=d
D= 224(substitute in the equation)
16t²= 224
t²= 224/16
t=√14
t= 3.7 seconds
