For this case we have the following equation of motion:
h (t) = -16t ^ 2 + 90t
Equaling the equation to zero we have:
-16t ^ 2 + 90t = 0
We look for the roots of the polynomial:
(t) (- 16t + 90) = 0
t1 = 0 (initial position)
t2 = 90/16 = 5.625 s (time it reaches the ground again)
Answer:
it will return to the ground in:
t = 5.625 s

Answer: You'll have 1/6 more food coloring than vanilla.
Step-by-step explanation:
You need to find the common denominator of 1/3 and 1/2, so multiply each denominator by each other. You'll have 3/6 food coloring and 2/6 vanilla, which means you'll have 1/6 more food coloring than vanilla.
