Problem 20PE

Problem 20PE

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 1.00×10−15 kg bacterium cling to the rim?

(d) Take the ratio of this force to the bacterium’s weight.

Step-by-Step Solution:

Solution 20PE

We are required to calculate the angular velocity of the tires, centripetal acceleration, centripetal force on a bacterium and the ratio of the centripetal force on the bacterium to its weight.

Part a

Step 1 of 5

Given data,

Linear speed of the jet m/s

Diameter of its tire  m

Radius  m

Angular velocity

rad/s

 rad/s

Now, 1 rev = 2 radians

141 radians  revolutions

1 min = 60 s

1 s = 1/60 min
