An object moving along a curve in the xy-plane has position (x(t) v(t))at time t with dy = 2+sin(€') The derivative & is not explicitly given Att= 3,the dt dt object is at the point (4,5). (a) Find the y-coordinate of the position at time t = 1 (6) At time t = 3,the value of dy is ~1.8. Find the value of & when t = 3. dx dt (c) Find the speed of the object at time t = 3.
