Question

A particle moves in a circular path of radius 0.2m with angular speed of 16rad/s. what is the centripetal acceleration of the particle? A. 51.2m/s2 B. 44m/s2 C. 42m/s2 d65m/s2

Answer 1

Centripetal acceleration a_c = ω^2 r.
ω = 16 rad/s → ω^2 = 256 (rad^2/s^2).
a_c = 256 × 0.2 = 51.2 m/s^2.

Answer: A. 51.2 m/s^2.
