Answer:
Step-by-step explanation:
Givens
a = 32 feet / second
vi = 0
d = 1472 feet
t = ?
Formula
d = vi*t + 1/2 a t^2
Solution
1472 = 0*t + 1/2 * a * t^2 Multiply both sides by 2
2944 = 32 * t^2 Divide by 32
2944/32 = t^2
92 = t^2 Take the square root of both sides
sqrt(t^2) = sqrt(92)
t = 9.59 seconds
