An object of mass 1.40kg attached to the act of a string is whirled round in a horizontal circle of radius 3.3m with a constant speed of 10m/s. Calculate the angular velocity.

To calculate the angular velocity, we can use the formula:

angular velocity (ω) = velocity (v) / radius (r)

In this case, the velocity is given as 10 m/s and the radius is given as 3.3 m.

Plugging in these values, we get:

ω = 10 m/s / 3.3 m
= 3.03 rad/s

Therefore, the angular velocity is 3.03 rad/s.
