**1. The problem statement, all variables and given/known data**

The coordinates of an object moving in the xy plane

vary with time according to the equations x =-5.00 sin (vt) and y= 4.00 – 5.00 cos (vt),

where v is a constant, x and y are in meters, and t is in seconds.

(a) Determine the components of velocity of the

object at t = 0. (b) Determine the components of

acceleration of the object at t = 0. (c) Write expressions

for the position vector, the velocity vector, and

the acceleration vector of the object at any time t > 0.

(d) Describe the path of the object in an xy plot.

**2. Relevant equations**

x =-5.00 sin (vt)

y= 4.00 – 5.00 cos (vt),

**3. The attempt at a solution**

I was able to solve all the parts of this question except part d.

I tried plotting the x y coordinates for different values of time, but the value of v is not provided. Should I consider some random value for v?

P.S: v actually has the angular velocity symbol in my book. (the abnormal w).
