Midterm 1 Review

September 28th 2007
I have not seen Professor’s final exam. Professor does not endorse this review
as good simulation of his exam. If you have a question about the review problems,
email Aritoki Suzuki at [email protected] I designed this midterm so it will
simulate midterm (2 hours, 6 problems). Good luck on a midterm exam.

1. Find velocity as function of time (find
vV
(
t
)
)
2. Find acceleration as function of time (find
va
(
t
)
)
3. Find time(s) when displacement is
0
m
4. Find average velocity between
t

and
t

5. Given
A
=

and
B
= 50
, at what time(s) speed =
