Is the force of static friction constant as the incline rises? Explain your answer. Q2:  If Mr. Einstein now wears ankle weights while sliding down, would the kinetic frictional force he experiences be the same, less, or greater than he experienced before? Would he accelerate faster? Would the coefficient of kinetic friction change?

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?”
