How does the distance traveled vary with time in uniform accelerated motion? (Hint: Solve Eq. 4.3 in the Laboratory Guide for d.)

Question 2

A metallic coin is given a negative electric charge. Its mass:
  1.increases measurably.
  2.increases by an amount too small to measure directly.
  3.remains unchanged.
  4.decreases by an amount too small to measure directly.
  5.decreases measurably.

Answer to Question 1

The distance traveled is proportional to the time squared. This is not a linear
relationship so a straight line will not be obtained is d is plotted as a function of t.
