How
to do the homework:
It is very
important that you understand the homework problems. Discussing with other
students is encouraged as long as you really comprehend what you are doing.
Copies from others or from the manual will not be accepted.

Hw 1
A: Ch.2: 13,17,…
Name: Your
Name
13- The
position of a particle moving along the x axis is given in centimeters
by x = 5 + 2 t 3, where t is in seconds. Consider
the time interval t = 2.00 s to t = 3.00 s.
a) Calculate the average velocity.
b)…
Solution
a)
The average v is delta x/ delta t
Delta x =x(3s) – x (2s) and delta t = 3s-2s = 1s
x(3) = 5+2 . 27 = 59
x(2) = 5+ 2 . 8 = 21
Then, delta x = 59-21 = 38m
Then, av. v = 38/1 = 38 m/s
b) …..
