A particle moves clockwise in a circle of radius 1m with centre at (x, y) = (1 m, 0). It starts at rest at the origin at time t = 0.
Its speed increases at the constant rate of `((n)/(2))" ms"^(2)`.
How long does it take to travel halfway around the circle?

Answer

(i) `t=2s`, (ii) `3.14 m//s`

Explanation

(a) `pi=0+1/2xxpi/2 t^(@)rArr t=2` sec
(b) `v=0+pi/2xx2=pi m//s`
