for the circular motion described by r(t) = (cos bt) i + (sin bt) j.
A) = -(sin bt) i + (cos bt) j and
= -(cos bt) i - (sin bt) j
B) = (sin bt) i + (cos bt) j and
= (cos bt) i - (sin bt) j
C) = -(sin bt) i + (cos bt) j and
= -(cos bt) i + (sin bt) j
D) = -(sin bt) i - (cos bt) j and
= -(cos bt) i + (sin bt) j
E) = (sin bt) i + (cos bt) j and
= -(cos bt) i + (sin bt) j
