Phys 101 Written Problems #10
Due: Fri, Dec 1, 2017 at 4 PM. Put finished assignment in P101 drop box on 9000 level of Physics (put
into the box that has your tutorial section number as a label).
Please note to get full credit for any written homework assignment you must:
1) Put the assignment name, your full name, your student number, your tutorial section number
(see Canvas for tutorial sections), and TA first name (-1 mark if not done correctly) :
PHYS 101 – Homework #1, Susie Smith, 123456789, D102, Tim
2) Show all of your work, clearly and legibly. Use diagrams if necessary.
3) Try to work out answers symbolically. Only put #s in at the end.
4) Put a box around your answers.
5) Don’t forget units.
6) If you use more than one page, staple all of the pages together (-1 mark for unstapled
assignments)
The end of a diving board can oscillate with a frequency of 2.9 Hz. Assume it behaves like a simple
harmonic oscillator in what follows.
Before we deal with the diving board, first consider you have a mass, m, on a spring with spring
constant, k, oscillating with a certain frequency, f and amplitude, A. Write down an equation for …
a) the magnitude of the maximum speed of the oscillator in terms of the frequency, f and the amplitude
of the oscillation, A. (2 marks)
b) the magnitude of the maximum acceleration of the oscillator in terms of the frequency, f and the
amplitude of the oscillation, A. (2 marks)
c) Now back to the diving board. You place a pebble on the end of the oscillating diving board. What is
the maximum amplitude that the board can oscillate with so that the pebble doesn’t lose contact with
the board at the top of the oscillation? (3 marks)
