Answer:
<em>The signal x[n] = 16000 samples</em>
Explanation:
From the question,
S = x/t ................................... Equation 1
making x the subject of the equation
x = St .................................. Equation 2
Where S = sample rate ( samples per seconds), x = signal (samples), t = time ( seconds)
<em>Given: S = 8000 samples, t = 2 seconds.</em>
<em>Substituting these values into equation Equation 2</em>
<em>x = 8000×2</em>
<em>x = 16000 samples.</em>
<em>Thus the signal x[n] = 16000 samples</em>
Answer:
m = 20[kg]
Explanation:
This problem can be solved, using kinematic equations and then applying Newton's second law. First we must find the acceleration and then replace it in the equation of Newton's second law.
Initial data:
Vo = initial velocity = 0 [m/s]
t = 3[s]
T- F = -m*a
T - m*g = m*a
We can assume a value for tension T equal to 196 [N].
Note: For this problem it is important to assume a tension value, otherwise, it is impossible to determine the value of mass m, in Newton's second law equation.
Construction, like building a home/building, digging, like in a mine, and opening a soda can, where the part to open is a lever.
Answer:
ax = -3.29[m/s²]
ay = -1.9[m/s²]
Explanation:
We must remember that acceleration is a vector and therefore has magnitude and direction.
In this case, it is accelerating downwards, therefore for a greater understanding we will make a diagram of said vector, this diagram is attached.
