be accepted.
It is very important that you SHOW YOUR WORK. Explain
clearly and briefly the steps you follow and why. The homework will be
graded based on the work you show on the page. If only the answer is given

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) �..
