A body of mass mis projected with speed u in a medium that exerts a resistance force of magnitude F = mk|v|. where k are positive constants and is the velocity of the body. Gravity can be ignored. Assuming that the motion starts from the origin and takes place along the positivex-axis, then which among the following state- ments is incorrect? The magnitude of velocity of body at time tis v = u kut+1 > 1 displacement of body at time tis x = -ln (kut +1) -In (kur+1) k The O The motion is bounded As t tends to infinity, displacement x tends to infinity
