Question
An electric fan goes from rest to $1800 \mathrm{rpm}$ in $4.0 \mathrm{~s}$. What is its angular acceleration?
Step 1
Given that 1 revolution = $2\pi$ radians, we can use the conversion factor: $1800 \mathrm{rpm} \times \frac{2\pi \mathrm{rad}}{1 \mathrm{rev}} \times \frac{1 \mathrm{min}}{60 \mathrm{s}} = 188.5 \mathrm{rad/s}$ Show more…
