If the answer marked does not obviously follow from the shown work, even if the answer is correct, you will not get credit for the answer. Sign below to indicate your understanding of the above rules. ~f (3, 4) = ( 1 2 4, 4 2 3)n. ~f (3, 4) = ( 9, 10)n (b) (8 points) find the single point of equilibrium of this potential. These are the points in which the force is zero. ) = ( 1 2y, 4 2x) = (0, 0) from which we get (x0, y0) = ( 2, . )m (c) (8 points) it is noticed that when the object is at position (5,3) the speed is s . Using conservation of energy, nd the speed of the object if it reaches.
