A student works an experiment using a force table apparatus for addition of vectors in two dimensions. Draw the graph and fill the empty space in the data table
a) Using the graph method (head-to tail method or parallelogram method), determine the resultant and equilibrant vector (magnitude and direction)
b) using the analytic method, determine the resultant and equilibrant vector ( magnitude and direction) find weight and mass.
