- Sketch the plane curve represented by the vector-valued function and give the orientation of the curve. r(B): = cos(6)i + 8 sin(6)j O -5 y 10 5 y 10 5 5 X X O -5 y 10 5 -5 y 10 5 X Xarrow_forwardUse Green’s Theorem to find the work done by the force field F on a particle that moves along the stated path. F(x,y)=√y i+√x j; the particle moves counterclock wise one time around the closed curve given by the equations y=0, x=2 and y=x3/4arrow_forwardThe position vector r describes the path of an object moving in the xy-plane. Position Vector Point r(t) = 4 cos ti + 4 sin tj (V5, 2V5) (a) Find the velocity vector v(t), speed s(t), and acceleration vector a(t) of the object. v(t) = -4 sin(t)i + 4 cos (2)j s(t) 4. -cos(1)i – 4 sin(r) a(t) = COS (b) Evaluate the velocity vector and acceleration vector of the object at the given point. -2V2 i+ 2V2jarrow_forward
