Consider the Sun to be at the origin of an xy-coordinate system. A telescope spots an asteroid in the xy-plane at a position given by (x, y) with a velocity given by (vx, vy).

[DATA: (x, y) = (3.3, 5.2) ×10^11 m;

(vx, vy) = (-6.1, -4.0) ×10^3 m/s.]

(A) What will the asteroid's speed be at closest approach (perihelion)?

(B) What will the asteroid's distance from the Sun be at closest approach?
