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
A
62.50ms-2
B
31.25ms-2
C
12.50ms-2
D
10.00ms-2
correct option: c
(\alpha = \frac{W_2 - W_1}{t} = \frac{5}{1} = 5 rad)/s2
9 = (\alpha)r
= 5 x 2.5 = 12.50m\s2
