A particle is rotating in a circle of radius R=(2π)R = \left(\frac{2}{\pi}\right) m, with constant speed 1 ms-1. Match the following two columns for the time interval when it completes 14\frac{1}{4} th of the circle.
Column IColumn II (SI units)
(a) Average speed(p) 2π\frac{\sqrt{2}}{\pi}
(b) Average velocity(q) 22π2\frac{\sqrt{2}}{\pi}
(c) Average acceleration(r) 2\sqrt{2}
(d) Displacement(s) 1
