Answer:
16/81
Step-by-step explanation:
Given the expression, 81y'' = -16y where y = coskt,
We want to know the value of k that satisfies the expression
y' = -ksinkt
y" = -k²coskt
Substitute y and y" into the expression given;
81y'' = -16y
81(-k²coskt) = -16(kcoskt)
-81k = -16
Divide both sides by -81
-81k/-81 = -16/-81
k = 16/81
Hence the value of k is 16/81
