Answer:
the angular speed in radian per second about the center of a circle is 0.278 rad/s
Explanation:
Given;
Linear velocity v = 25m/s
Radius of circular path r = 90m
The linear velocity of the particle can be expressed as a function of the angular speed as;
Linear velocity = angular speed × radius of path
v = wr
w = v/r
Where;
v = linear velocity
r = radius
w = angular speed
Substituting the given values, we have;
w = 25/90 = 0.278 rad/s
the angular speed in radian per second about the center of a circle is 0.278 rad/s
