Answer:
V initial = 29.4 m.s²
Explanation:
( Using the laws of motion)
V final = V initial + Acceleration × time
0 = V initial + ( -9.8)(3)
29.4 = V initial
* I took upward as positive that's why I substituted -9.8 *
* for V final we know that at maximum height the ball is not moving thats why is = 0 *
Pitch is related to frequency
For the given question above, there are other details that is missing. Here is what I got from my research.
Mass of a hydrogen atom as 1.008 u,
<span>where 1 u=1.661 times 10^-27 kg.
</span>The frequency of a mass on a spring is:
<span>f = omega / 2pi = sqrt (k/meff) / 2pi </span>
<span>The meff you use is the effective mass. If two bodies with mass M and m are both free to move: </span>
<span>Meff = Mm / (M+m) </span>
<span>If M=m, then Meff = m/2 (as you were given) </span>
<span>So the answer is: </span>
<span>f = sqrt (2k/m) / 2pi </span>
