Assume your sampling frequency (fs) is 500 Hz. If you want to capture the 50Hz signal for 5 seconds, calculate the number of sam
belka [17]

Answer:

N = 2500

Explanation:

By definition, the sampling frequency (fs) is:

f_{s} = N / T

<em>where N: is the number of samples and T: is the time</em>

Hence, the number of samples at the sampling frequency, 500 Hz, to get 5 seconds of data is:

N = f_{s} \cdot T = 500 s^{-1} \cdot 5 s = 2500  

I hope it helps you!

A 40.0 kg child is in a swing that is attached to ropes 2.00 m long. Find the gravitational potential energy associated with the
o-na [289]

Answer:

A. As the ropes are horizontal the child has travelled 2m of vertical displacement from his lowest position.

Gpe @ A=mgh=40*9.81*2=784.8J

B. At 30degree vertical angle the vertical displacement from lowest position is given by

2-2cos(30)=2-1.73=0.27m

Gpe @B= 40*9.81*0.27=106 J

C: at the bottom of circular arc it's Gpe is zero relative to lowest position as bottom of arc itself is lowest position.

a shot putter accelerates a 7.3kg shot from rest to 14m/s in 1.5r seconds. what average power was developed?
Sedaia [141]

Explanation:

power =  \frac{energy \: expended}{time}

m = 7.3kg

u = 0

v = 14m/s

t = 1.5sec

P = (0.5×7.3×14²) ÷ 1.5

P = 476.93

P = 477 watt
