A constant horizontal force of 21 N pushes a 5 kg-mass through a medium that resists its motion with 0.7 N for every m/s of speed. The initial velocity of the mass is 8 m/s in the direction opposite to the direction of the applied force. Find the velocity of the mass at any time,t, and the time at which the 5 kg-mass will stop moving.
