For this case we have the following equation:
h (t) = at ^ 2 + v * t + h0
Substituting values we have:
h (t) = - 16 * t ^ 2 + 60 * t + 3
We equate the equation to zero:
-16 * t ^ 2 + 60 * t + 3 = 0
We look for the roots of the polynomial:
t1 = -0.04935053979258153
t2 = 3.7993505397925817
We are left with the positive root and round:
t2 = 3.8 s
Answer:
t = 3.8 s
option 3
#1 center (9,6) radius = 10
#2 center (4,-2) radius = 4 square root 2
#3 center (-3,-8) radius = 9
#4 center (-6,5) radius = 2 square root 2
y=mx+b plus in slope and you get your answer
