1.6km = 1 mike? Wow that guy is tall.
I think you meant 1.6 km = 1 mile? Okay then if we're going 12 meters per second how much would you travel in one hour? First we need to figure out how many seconds are in an hour. There are 60 seconds in a minute and 60 minutes in an hour so:
60×60=3600 seconds in an hour
Now we will multiply that by 12 meters per second and we get:
And 43200 meters is 43.2 km (1000 meters in 1 kilometer) meaning 43.2 kilometers an hour. Since there are 1.6 km in one mile we must divide 43.2km to 1.6.
And so your speed is 27 miles per hour.
Answer:
ω = 22.36 Hz
f = 3.56 Hz
T = 0.28 s.
Explanation:
a) The angular frequency (ω), can be calculated using the following equation:
<u>Where:</u>
<em>k: is the spring constant = F/x</em>
<em>m: is the mass of the particle = 0.500 kg</em>
<em>F: is the force applied = 7.50 N </em>
<em>x: is the displacement = 3.00 cm = 0.03 m </em>
Therefore, the angular frequency of the motion is 22.36 Hz.
b) To find the frequency (f) we can use the next equation:
Hence, the frequency of the motion is 3.56 Hz.
c) The period (T) is equal to:
Therefore, the period of the motion is 0.28 s.
I hope it helps you!
