Answer:
a = L
b = MT^(-1)
c = LT^(-1)
k = MT^(-2)
f = MLT^(-2)
S = T^(-1)
Step-by-step explanation:
x (0) = a
x is denoted by displacement in vibration analysis hence attains units of x.
Hence, a = L
b is the damping coefficient:

x'(0) = c
dx/dt = velocity hence c attains the units of velocity
c = LT^(-1)
Coefficient k is the stiffness:

Coefficient f is the magnitude of the exciting force

Coefficient S is the angular frequency
angular frequency is displacement in radians per seconds; hence,
S = T^(-1)
66 is ure answer because im a math expert
Answer:
9/20
Step-by-step explanation:
Your answer for -16 divided by 2 will be -8, because half of 16 is 8, but you are just in the negative numbers:)! So your answer is -8
