Two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kilogram. If they pull in the similar direction, the boat has an acceleration of 1.59 m/s2 to the right. If they pull in opposite directions, the boat has an acceleration of 0.509 m/s2 to the left. Find the magnitude of the force each person exerts on boat? Disregard any other horizontal forces on the boat.
