Hooke's law states that F = -kx, so
<span>k = - F/x = - ma / x = - 2.6kg · (-9.8m/s²) / (0.041m) = 621 N/m ← (a) </span>
<span>(b) f = (1/2π) · sqrt(k/m) = (1/2π) · sqrt(621N/m / 2.6kg) = 2.46/s = 2.46Hz </span>
<span>Amplitude is simply 2.1cm</span>

Answer:
f(x) = x³ +3x² -6x -18
Step-by-step explanation:
In order for there to be a root of √6, there must be a factor of (x-√6). In order for there to be rational coefficients, there needs to be another factor of (x+√6) in the minimal polynomial. Then the minimal polynomial with the required roots is ...
f(x) = (x +3)(x -√6)(x +√6) = (x +3)(x² -6)
f(x) = x³ +3x² -6x -18
The answer is 7, 3 plus 1 equals 4 minus four equals zero plus 7= 7
