| This guy doesn't know when to quit. Since he causes friction wherever he speaks and his words carry little weight, it's not unusual for his audience to find unique ways to cut his speeches short.
Speaking of friction and weight, our orator weighs 800 N and is standing firmly on the 100-N crate as it is being pulled away. If the truck is accelerating (backwards) at 4 m/s2, what is the minimum coefficient of static friction between the crate and the orator's shoes? |
