E = 300km * 2000J/km = 600000J
The rotational energy is given by:
E = 0.5 * I * ω²
I for a uniform cylinder is given by:
I = 0.5 * m * r²
Resulting equation:
E = 0.25 * m * r² * ω²
Given values:
ω = 430 rev/s = 430 * 2π / s
E = 600000
Solve for r.

Gravity pulling it down or the air cd (carbon dioxide)
Answer:
[a]
F=ke
E= 5/100=0.05m, m=2kg, F=mg[2x9.8]=19.6N
Spring constant[K] =F/e
K=19.6/0.05
K=392N/m
