Find the angular speed of a point traveling through theta ra

Find the angular speed of a point traveling through theta radians in time t. theta = 39pi/2, t = 2.5 hr The angular speed is radians/hr. (Simplify your answer Use integers or fractions for any numbers in the expression. Type an exact answer, using pi as needed.)

Solution

Angular Speed = = /t

= 39/2.5 x 2

= 39 x 22/35 = 39 x 0.6 = 23.4rad/hr
