A body is rotating in a horizontal circle of radius 2.5m with an angular speed of 5 rad s-1. Calculate the magnitude of the radial acceleration of the body
- 62.50ms-2
- 31.25ms-2
-
12.50ms-2
- 10.00ms-2
The correct answer is: C
Explanation
\(\alpha = \omega^2\)r
= 5\(^2\) x 2.5 = 25 x 2.5 = 62.5ms\(^{-2}\)
