PHSX 114 – HOMEWORK #4 Question 1: (1 point) If V x = 13.6 units and V y = -7.30 units. Enter only numbers in your answer. (Do not include units.) a. Determine the magnitude of . units b. Determine the direction of from East. Enter only positive values and choose the direction relative to the positive x-axis from the drop-down menu. Enter scientific notation as 1.23E4. degrees HINT: The figure presented is only representative for a particular data set. Each run of this algorithm will produce unique vectors along the x and y axes that can differ widely in terms of magnitude and direction. Question 2: (2 points)
