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 rpm are the tires rotating? in rpm?

(b) What is the centripetal acceleration at the edge of the tire? in m/s2 ?

(c)With what force must a determined 10−15 kg bacterium cling to the rim? in N?

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

(force from part (c)/bacterium's weight)

A bicycle wheel in the shape of a hoop has a diameter of 1.00 m and a weight of 37.0 N. The bicycle is placed on a stationary stand. The wheel starts rotating from rest with a constant angular acceleration of 2.20 rad/s2. Consider a dust particle stuck on the rim of the wheel. (a) At t = 0.710 s, determine the magnitude of the centripetal acceleration of the dust particle. m/s2 (b) At t = 0.710 s, determine the...

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...

a- What is the maximum speed with which a 1200-kg car can round a turn of radius 90.0 m on a flat road if the coefficient of static friction between tires and road is 0.60? Part b If the jet is moving at a speed of 1140 km/h at the lowest point of the loop, determine the minimum radius of the circle so that the centripetal acceleration at the lowest point does not exceed 6.0 g's. Express your answer to...

The Cosmoclock 21 Ferris wheel in Yokohama City, Japan, has a diameter of 100 m. Its name comes from its 60 arms, each of which can function as a second hand (so that it makes one revolution every 60.0 s). A- Find the speed of the passengers when the Ferris wheel is rotating at this rate. B- A passenger weighs 897 N at the weight-guessing booth on the ground. What is his apparent weight at the lowest point on the...

1. Starting from rest, a CD takes 3.0 s to reach its operating angular velocity of 450 rpm. The mass of a CD is 17 g and its diameter is 12 cm. You may assume that the small opening at the center of the CD is unimportant when calculating the rotational inertia. Assume that the angular acceleration is constant. a. What is the rotational kinetic energy of the CD after it has completely spun up? b. How high off the...
