MA 126 Midterm: Cal_II_MA_126_8C_test_4 Fall 2016
Document Summary
Closed book - calculators and one index card are allowed! Clearly write your answer (only) in the space provided after each question. Very limited partial credit or none at all for this part of the test! Find both the scalar projection compvu and the vector projection projvu of the vector u = h1, 1, 1i onto the vector v = h1, 0, 1i. A constant force with vector representation f = 2i j + 4k moves an object along a straight line from the point p (1, 1, 1) to the point q(1, 2, 1). Find the work done if the distance is measured in meters and the magnitude of the force is measured in newtons. Find the parametric equations of the line that passes through the point p ( 1, 1, 0) and that is perpendicular to the vectors u = h1, 0, 1i and v = h0, 1, 1i.
