Thanks a lot your explanations are excellent.13.Two people start at the same place and walk around a circular lake in opposite directions. One has an angular 

 

speed of 2.63 x 10

 

-3

 

 rad/s, while the other has an angular speed of 4.07 x 10

 

-3

 

 rad/s. How long will it be before they 

 

meet?

 

At a county fair there is a betting game that involves a spinning wheel. As the drawing shows, the wheel is set into 

 

rotational motion with the beginning of the angular section labeled "1" at the 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 into twelve sections, each of which is an angle of 30?. Determine the numbered section on which the wheel 

 

comes to a halt when the deceleration of the wheel has a magnitude of 0.268 rev/s

 

2

 

 and the initial angular velocity is 

 

(a)

 

 +1.19 rev/s and 

 

(b)

 

 +2.62 rev/s. 

 

A fan blade is rotating with a constant angular acceleration of +10.6 rad/s

 

2

 

. At what point on the

 

blade, as measured from the axis of rotation, does the magnitude of the tangential acceleration

 

equal that of the acceleration due to gravity?

 

A fisherman is reeling in a fish. In 6.2 s he winds 2.7 m of fishing line onto a reel whose radius is 4.7 cm (assumed to 

 

be constant as an approximation). The line is being reeled in at a constant speed. Determine the angular speed of the

 

reel.
