The angular speed of an object describes a circle of radius 4m with linear constant speed of 10m/s is
A
2.50 rads\(^{-1}\)
B
1.58 rads\(^{-1}\)
C
14.00 rads\(^{-1}\)
D
40.00 rads\(^{-1}\)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Linear speed = \(\omega\) r
\(\omega\) = \(\frac{\text{v}}{\text{r}}\)
\(\omega\) = \(\frac{10}{4}\) = 2.5 rads\(^{-1}\)
