You have setup an experiment with two 50g masses attached to strings that are connected on opposite sides of a scale that measures weight in Newtons.
a.) What is the reading on the scale?
b.) The whole system is now moving to the left at a speed of 10m/s. What is the reading on the scale?
c.) The whole system is now moving to the right at a speed of 50m/s. What is the reading on the scale.
