1. The problem statement, all variables and given/known data A gyroscope takes 3.8 s to precess 1.0 revolution about a vertical axis. Two minutes later, it takes only 1.9 s to precess 1.0 revolution. No one has touched the gyroscope. Explain 2. Relevant equations ω = Δθ/Δt ω = ωo + at 3. The attempt at a solution So is the gyroscope accelerating more? But in what direction?
