the angular speed of an automobile engine is increased at a constant rate from $1200 \mathrm{rev} / \mathrm{min}$ to $3200 \mathrm{rev} / \mathrm{min}$ in $12 \mathrm{~s}$. (a) What is its angular acceleration in revolutions per minute-squared? (b) How many revolutions does the engine make during this $12 \mathrm{~s}$ interval?
