Two teams, competing in tug-of-war, apply forces equal in magnitude to it
a) What is the resultant of these forces?
b) The rope broke when both teams pulled it with 800 N forces. Can one team break the rope by applying 800 N force?
a) 0; b) can. Solution, a) The resultant of two equal in magnitude and oppositely directed forces is zero, b) If one end of the rope is tied to a pole and the other is pulled with a force of 800 N, then according to Newton’s third law, the pole will also act on the rope with a force of 800 N. Thus thus, the same forces will act on the rope as the two teams applied; therefore, one team can break the rope.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
