A 70 kg person is having a tug-of-war. The rope is horizontal and 1.3 m above the ground. This person’s center of mass is 1.0 m from the ground when he is in an upright standing position. If the force his opponent exerts on the rope is 400 N, what angle must the person be from...

Two people are pulling a boat through the water as in the figure below. Each exerts a force of 600 N directed at a è = 20.0° angle relative to the forward motion of the boat. If the boat moves with constant velocity, find the resistive force exerted by the water on the boat.
