The coordinates of an object moving in the xy-plane vary with time according to the equations x = −9.14 sin ωt and y = 4.00 − 9.14 cos ωt, where ω is a constant, x and y are in meters, and t is in seconds.
(a) Determine the components of the velocity of the object at t = 0.
(b) Determine the components of the acceleration of the object at t = 0.
