marker at the top of the wheel. The wheel then decelerates and eventually comes to a halt on one of the numbered sections. The wheel in the drawing is divided in to twelve sections with 30 degrees in each section. Determine the numbered section on which the wheel comes to a halt when the deceleration of the wheel has a magnitude of 0.3 rev/s2 and initial angular speed is 7 rev/s. (Attached the photo is the drawing) The marker stops ate REGION:

A circular track has several concentric rings where people can run at their leisure. Phil runs on the outermost track with radius rP while Annie runs on an inner track with radius rA = 0.70 rP. The runners start side by side, along a radial line, and run at the same speed in a counterclockwise direction. How many revolutions has Annie made when Annie's and Phil's velocity vectors point in opposite directions for the first time?

The tires of a car make 82 revolutions as the car reduces its speed uniformly from 96 km/h to 63 km/h. The tires have a diameter of 0.70 m. If the car continues to decelerate at this rate; how much more time is required for it to stop? (Your result must be in seconds and include 1 digit after the decimal point. Maximum of 2% of error is accepted in your answer.)

An electric fan rotates at the rate of 850 rev / min when it is turned off. After turning off, it spins 1350 revolutions before stopping. How long did it take for the fan to stop completely?

A car travels at a constant speed around a circular track whose radius is 3.51 km. The car goes once around the track in 259 s. What is the magnitude of the centripetal acceleration of the car?

A wheel starts from rest with a constant acceleration. It completes one complete revolution in 5 seconds. After how much time (after being started) will it complete 7 revolutions.

A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 35 m. The runner starts the race at a constant speed. If she completes the 200 m dash in 22.6 s and runs at constant speed throughout the race, what is the magnitude of her centripetal acceleration (in m/s2) as she runs the curved portion of the track?

A Ferris wheel with a radius of 24.0 m is turning about a horizontal axis through its center as shown in the figure. The speed of a passenger on the rim is constant and equal to 6.00 m/. What is the magnitude and direction of the passenger's acceleration as she passes through the (a) lowest point in her circular motion and by the highest point in her circular motion? (c) How much time does it take the Ferris wheel to make one revolution? (d) Include a diagram of the passenger on the Ferris wheel at both locations and clearly indicate both the velocity and acceleration vectors of the passenger in the diagram

A wheel with a radius of 18.0 cm rolls without slipping along a horizontal floor (see the figure). At time t₁, the dot P painted on the rim of the wheel is at the point of contact between the wheel and the floor. At a later time t2, the wheel has rolled through one-half of a revolution. What are (a) the magnitude and (b) the angle (relative to the floor) of the displacement of P during this interval? (a) Number i 67.0 (b) Number 32.5 Units Units At time m ° (degrees) P At time to
