A body moves along a circular path with uniform angular speed of 0.6 rads−¹ and at a constant speed of 3.0ms−¹. Calculate the acceleration of the body towards the centre of the circle.

A. 25.0ms−²
B. 5.4 ms−²
C. 5.0ms−²
D. 1.8 ms−²
E. 0.2ms−²

Correct Answer:

Option D – 1.8 ms−²

Explanation

A = wv = 0.6 x 3.0 = 1.8m−²
