plication of +y b Physics nts Vector Ais shown Which of the following options represents A, the z component of vector A7 O A cos(a) and this is a negative number O Asin(a), and this is a negative number O A cos(a) and this is a postive number O Asin(a), and this is a positive number

M PRACH Consider the three displacement vectors A = (4î - 3ĵ) m, B = (61 - 7ĵ) m, and C = (-8î + 5ĵ) m. Use the component method to determine the following. (Take the +x direction to be to the right.) (a) the magnitude and direction of the vector D = A + B + C X magnitude Note that all three vectors lie in the xy plane so the sum of these vectors will also lie in the xy plane. m X The angle you give does not put the sum into the correct quadrant.° counterclockwise from the +x axis direction (b) the magnitude and direction of E= -A-B+C magnitude m direction counterclockwise from the +x axis

Ө TA TU 135° B Ā Suppose that the magnitude of À is 36.0 km and the magnitude of Ċ is 25.0 km. If the total lisplacement vector Ď has a magnitude of 62.0 km, determine the angle (which gives the lirection of Ď) and determine the magnitude of B.
