A constant horizontal force Fa pushes a 3.40 kg FedEx package across a frictionless floor on which an xy coordinate system has been drawn. The figure below gives the package's x and y velocity components versus time t. (The vx axis is marked in increments of 1.25 m/s and the vy axis is marked in increments of 1 m/s.)
