Circumference=pi*2r = 3.14 * 20=62.83 m.
d = (270o/360o) * 62.83m = 47.12 m. =
Distance traveled.
d = r*t = 47.12 m.
r = 47.12/t = 47.12/20 = 2.36 m/s=Speed.
Displacement = 10m[270] - 10[0o]
-10 - 10i = -14.14m.[45o] = 14.14m[-45o]
Ana run in a circular path. The dimension of the circular path is r = 10m , she finished it in 20 seconds. Find his speed, distance, displacement and velocity.
