Newton's laws

  1. Sep 29, 2014 #1
    1. The problem statement, all variables and given/known data
    Adam and Ben pull hand over hand on opposite sides of a rope while standing on a frictionless pond.
    Adam's mass: 75.0kg
    Ben's mass: 50.0kg
    Adam's acceleration: 1.00 m/s2 to the east
    What is the magnitude and direction of Ben's acceleration?

    Did you attempt to do the problem yourself? What principles do you think you should apply to this problem?

    the second law of motion? I don't know where to start.

    You certainly can use the second law of motion. Let's start there. If Adam's acceleration is 1 m/s2 east, what does the second law say about the force exerted on him?

    force would be 75.0kg( 1 m/s2)

    If this is the force the rope exerts on Adam, how much force does Adam exert on the rope?
