A particle is moving counterclockwise around the circle x2 + y2 = 9 at constant speed, making one revolution in 2 seconds, At t = 0, the
particle is at the point (0,3). Find position vector r(t) of this motion when t € R.
Find also velocity, v(t), and acceleration, a(t), of this motion.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
