The coordinates of an object moving in the xy plane vary with time according to the equations

x = −6.85 sin ùt and y = 4.00 − 6.85 cos ùt,

where ù 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. (Use the following as necessary: ù.)

(b) Determine the components of the acceleration of the object at t = 0. (Use the following as necessary: ù.)

(c) Write expressions for the position vector, the velocity vector, and the acceleration vector of the object at any time t > 0. (Use the following as necessary: omega for ù and t.)

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