Hints for HW 3
General Advice: The mathematical skills you need for this
problem set include algebra and how to determine the maximum of a
function by taking derivatives.
Hints on specific problems:
- Problem 3-15: Understand the figure!
- Problem 3-16: It is easiest to work out your algebra in terms
of the unknown delta t, and then replace it with things you can measure
at the end of your calculations. Once again understand the figure.
If you have trouble solving part d, try to plot out some results.
Calculus is needed for part e. Measure data from the figure for part g.
- Problem L-12 It is critical that you can construct an equation
for the rod moving in the lab frame, in order to complete this problem.
For example, if the rod is length L, and sitting with its right tip at the
origin, then an equation for the rod is f(x)=x for -L is less than x is less
than 0.
- Problem 4-2 Draw a figure, and be sure you know what frame
you are in at each moment.
