A constant horizontal force F a pushes a 4.90 kg FedEx package across a frictionless floor on which an xy coordinate system has been drawn. The figure gives the package's x and y velocity components versus time t. What are the (a) magnitude and (b) direction of Fa? Give the direction as a positive or negative angle of magnitude less than 180° relative to the +x-axis. V. (m/s) v., (m/s) 1 2
