Problem 4.11: Modified Atwood's machine

Please wait for the animation to completely load.

A 1.0-kg cart (not shown to scale) on a low-friction track is connected to a string and a hanging object as shown in the animation. Neglect any effects of the pulley on the motion of the system (position is given in meters and time is given in seconds). Restart.

  1. What is the tension in the string?
  2. What is the mass of the hanging object?

Note that the coordinates for each object (the positive x direction) are already chosen for you.
