Answer:
m = 1.99 kg = 2 kg
Explanation:
The moment of inertia of a bicycle rim about it's center is given by the following formula:
![I = mr^{2}\\](https://tex.z-dn.net/?f=I%20%3D%20mr%5E%7B2%7D%5C%5C)
where,
I = Moment of Inertia of the Bicycle Rim = 0.21 kg.m²
r = Radius of the Bicycle Rim = Diameter of the Bicycle Rim/2
r = 0.65 m/2 = 0.325 m
m = Mass of the Bicycle Rim = ?
Therefore,
![0.21\ kg.m^{2} = m(0.325\ m)^{2}\\m = \frac{0.21\ kg.m^{2}}{(0.325\ m)^{2}}\\](https://tex.z-dn.net/?f=0.21%5C%20kg.m%5E%7B2%7D%20%3D%20m%280.325%5C%20m%29%5E%7B2%7D%5C%5Cm%20%3D%20%5Cfrac%7B0.21%5C%20kg.m%5E%7B2%7D%7D%7B%280.325%5C%20m%29%5E%7B2%7D%7D%5C%5C)
<u>m = 1.99 kg = 2 kg</u>
I'd say B since headland since whenever there's a crash wave, headland receives most of the impact

The maximum speed the mass can have before it breaks is 2.27 m/s.
The given parameters:
- <em>maximum mass the string can support before breaking, m = 17.9 kg</em>
- <em>radius of the circle, r = 0.525 m</em>
The maximum speed the mass can have before it breaks is calculated as follows;
![T = ma_c\\\\Mg = \frac{Mv^2}{r} \\\\v^2 = rg\\\\v = \sqrt{rg} \\\\v_{max} = \sqrt{0.525 \times 9.8} \\\\v_{max} = 2.27 \ m/s](https://tex.z-dn.net/?f=T%20%3D%20ma_c%5C%5C%5C%5CMg%20%3D%20%5Cfrac%7BMv%5E2%7D%7Br%7D%20%5C%5C%5C%5Cv%5E2%20%3D%20rg%5C%5C%5C%5Cv%20%3D%20%5Csqrt%7Brg%7D%20%5C%5C%5C%5Cv_%7Bmax%7D%20%3D%20%5Csqrt%7B0.525%20%5Ctimes%209.8%7D%20%5C%5C%5C%5Cv_%7Bmax%7D%20%3D%202.27%20%5C%20m%2Fs)
Thus, the maximum speed the mass can have before it breaks is 2.27 m/s.
