Answer: Got It!
<em>Explanation: </em>let s = speed at launch
v = 0 at top = s sin 63 - g t
so at top
t = s sin 63/g = .0909 s
h = 13.6 = s sin 63 t - 4.9 t^2
13.6 = .081s^2 - .0405 s^2
s^2 = 336
s = 18.3 m/s
0 0

Answer:
0.356 times the mass pass through equilibrium per second.
Explanation:
Given that,
Spring constant = 10 N/m
Mass = 2 kg
Stretched spring = 2m
We need to calculate the frequency
Using formula of frequency
Where, m = mass
k = spring constant
Put the value into the formula
We know that,
Hertz = cycle per second
Hence, 0.356 times the mass pass through equilibrium per second.
