One of you faggots wanted to know in an earlier thread what would happen when all the people on Earth would start running in one direction. Here's the answer:
Generalisation: 7b - population 75 kg - avg weight 3 m/s - topspeed 3 s - acceleration time
6378 km - Earth's equator radius, lets have everyone there 5,974E24 kg - Earth's mass 0.3308 mr²- Earth's Moment of inertia (Source: Nasa Earth fact sheet) 7.292115E-5 rad/s Earth's rotational speed (Source: wolframalpha) Losses - losses are niggers, I hate niggers, so I'm not gonna account for them. Fucking niggers.
Calculate: Force F = m · a = 7b · 75 kg · 3m/s² = 1.575 TN Torque M = F · s = 1.575 TN · 6,378 km = 1.05 PNm Angular acceleration α = M ÷ J = 1.05 PNm ÷ (.3308 · 5,974E24 kg · (6,378,000 m)²) = 1.24958E-19 rad/s² Angular speed difference Δω = α · Δt = 1.24958E-19 rad/s² · 3 s = 3.74875E-19 rad/s
