Answer

Rope tension is discussed on page 30. The tension in the rope is 250 N. With no acceleration, each person must experience a zero net force. This can happen if each feels a horizontal frictional force of 250 N from the ground. By Newton's third law, each is pushing against the ground with a force of 250 N.
