Question

An object moves in the xy-plane with coordinates: x  4cos(20t) (m) and
y  4sin(20t) (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.
