The drill used by most dentists today is powered by a small air-turbine that can operate at angular speeds of 302000 rpm. These drills, along with ultrasonic dental drills, are the fastest turbines in the world - far exceeding the angular speeds of jet engines. Suppose a drill starts at rest and comes up to operating speed in 2.17 s. Calculate the angular acceleration produced by the drill, assuming it to be constant. Give answer in rev/s. Do not enter unit.
Consider a thin, uniform rod of mass m and length L (and negligible other dimensions) lying on the x axis (from x=-L to 0). Derive a formula for the gravitational ?eld “g” at any arbitrary point x to the right of the origin (but still on the x-axi..
