For a body in a circular motion with a constant angular velocity, the magnitude of the average acceleration over a period of half a revolution is...... times the magnitude of its instantaneous acceleration

a) 2/π

b) π/2

c) π

d) 2

Answer: a) 2/π


Average acceleration, aavg = ΔV/ Δt

= 2ωR/(πR/ωR)


Instantaneous acceleration, ai = ω2R

(aavg /ai)=2/π
