ratio of angular speed of minute hand and hour hand of a watch is. (a) 6:1 (b) 1:6 (c) 1:12 (d) 12:1

Angular speed (ω) is related to speed (v) as:  v = r × ω, where r is radius.   Determine the dimension of angular speed ω in terms of [L], [M], [T].

Suppose the width of your fist is 6.4 inches and the length of your arm is 32.6 inches. Based on these measurements, what will be the angular width (in degrees) of your fist held at arm’s length?

The angular position of a point on a rotating wheel is given by θ = 5.81 + 8.13t2 + 3.45t3, where θ is in radians and t is in seconds. At t = 0, what are (a) the point's angular position and (b) its angular velocity? (c) What is its angular velocity at t = 8.75 s? (d) Calculate its angular acceleration at t = 1.09 s. (e) Is its angular acceleration constant?
