MA 126 Midterm: MA_126_test4 Fall 2015
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 the angle between the vectors u = h1, 1, 1i and v = h1, 1, 0i. (write your angle in degrees or radians!) A constant force with vector representation f = 3i + j + 5k moves an object along a straight line from the point p (1, 1, 1) to the point q(3, 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 symmetric equations of the line that is perpendicular to the plane x y z = 2 and passes through the point ( 1, 1, 0).
