Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

Suppose a 50.5 kg gymnast climbs a rope.
(a) What is the tension (in N) in the rope if he climbs at a constant speed?
N
(b) What is the tension (in N) in the rope if he accelerates upward at a rate of
1.35 m/s2?
