Question
At takeoff, a commercial jet has a 60.0 m/s speed. Its tires have a diameter of 0.850 m. (a) At how many rev/min are the tires rotating? (b) What is the centripetal acceleration at the edge of the tire? (c) With what force must a determined $1.00 \times 10^{-15}\textrm{ kg}$ bacterium cling to the rim? (d) Take the ratio of this force to the bacterium's weight.
1. $1350 \textrm{ rev/min}$
2. $8.47 \times 10^{3}\textrm{ m/s}^2$
3. $8.47 \textrm{ -12} \textrm{ N}$
4. $864$
