Question

An object moves in the xy-plane with coordinates:
x = 4cos(20 t) (m )
and
y =4sin(20 t) (m ) .
a/ Find the object’s distance from the the origin and the speed of the object at every instant of time. Deduce
the characteristics of this motion.
b/ Determine the magnitude and the direction of the acceleration vector at each instant of time.
c/ Sketch the trajectory of this object with the velocity vector and acceleration vector at some instant of time t.
