96. REASONINGThe magnitudeFΣof the net force acting on the kayak is given by Newton’s second law as FmaΣ=(Equation 4.1), where mis the combined mass of the person and kayak, and ais their acceleration. Since the initial and final velocities, v0and v, and the displacement xare known, we can employ one of the equations of kinematics from Chapter 2 to find the acceleration. SOLUTIONSolving Equation 2.9
