also displayed the effects of sound being an invisible force of our world. Sound are frequencies. Different frequencies shape matter differently as you’ve seen.
Now, the human ear can only hear frequencies to a certain extent. When you take a hearing test at the doctors, they test your hearing by playing different tones (frequencies) in your ear. As people get older they will not be able to hear higher frequencies.
k = 5.29
a = 0.78m/s²
KE = 0.0765J
<u>Explanation:</u>
Given-
Mass of air tracker, m = 1.15kg
Force, F = 0.9N
distance, x = 0.17m
(a) Effective spring constant, k = ?
Force = kx
0.9 = k X0.17
k = 5.29
(b) Maximum acceleration, m = ?
We know,
Force = ma
0.9N = 1.15 X a
a = 0.78 m/s²
c) kinetic energy, KE of the glider at x = 0.00 m.
The work done as the glider was moved = Average force * distance
This work is converted into kinetic energy when the block is released. The maximum kinetic energy occurs when the glider has moved 0.17m back to position x = 0
As the glider is moved 0.17m, the average force = ½ * (0 + 0.9)
Work = Kinetic energy
KE = 0.450 * 0.17
KE = 0.0765J
Let's see

Now we know the formula of acceleration
