Question
Problem 1:
A meter stick has mass m = .2 kg (distributed uniformly along its length) and a length of (of
course) 1 meter. The stick is placed simultaneously on two weight scales: one at the 20 cm
mark (with 0 cm at the far left end of the stick), the other at the 70 cm mark, with no other
supports or weights. Remember that a weight scale supplies an upward force, equal to the
reading on the scale.
Calculate the reading on both scales. Call the reading on the left scale (at 20 cm) FL, and
the reading on the right scale (at 70 cm) FR.
