1. A flywheel is rotating at 7 rad/sec. It has a 15-cm diameter. What is the speed of a point on its rim, in cm/min? 2. A wheel is rotating at 3 radians/sec. The wheel has a 30 cm radius. What is the speed of a point on its rim, in m/min?

10. A plane travels 79 mi at a bearing of 37° 19'. How far north did the plane travel during that time? OA. 48 mi OB. 99 mi C. 63 mi OD. 36 mi

23. An object is travelling at a certain velocity, as shown in the diagram. The vertical component of its velocity is 42km/h. What is the magnitude of the resultant velocity of the object (R)? Round to one decimal. 37°

Ex. 5 A bicycle wheel turns at a rate of 90 revolutions per minute (rpm). Determine the angular velocity, expressed in a) degrees per second and b) radians per second Angular velocity (w) is the rate at which the central angle is changing. 0 @=I t
