A particle travels along a straight line with a velocity,
v=(6t-3t^(2))[(m)/(s)]
, where
t
is in seconds. The initial conditions are
s=0
at
t=0
. (a) At
t=3s
, compute the acceleration and position. Solution:
a=-12(m)/(s^(2)),x=0
(b) What is the total distance traveled during the
3-s
interval? Solution:
S_(TOT)=8m
(c) What is the average speed over the 3-s interval? Solution:
(V_(SP))_(AVG)=2.67(m)/(s)
