Explanation / Answer

Here,

angular speed , w = 1 rev/s

w = 2pi rad/s

a = - 0.03 rad/s^2

let the time taken is t

0 = w - a * t

0 = 2pi - 0.03 * t

t = 209 s

the time taken is 209 s

2)

NOw, for the angle rotated

angle = 0.50 at^2

angle = 0.50 * 0.03 * 209^2

angle = 655.2 radian

angle = 104.3 revolutions

the angle is 104.3 revolutions
