Question
Q2/A dog running in an open field has
components of velocity Vx = 2.6 m/s
and Vy = -1.8 m/s at t1 = 10.0 s. For the
time interval from t1 = 10.0 s to t2 =
%3D
%3D
20.0 s, the average acceleration of
the dog has magnitude 0.45 m/s2
and direction 31o measured from the
+x-axis toward the +y-axis. At t2 =
20.0 s, (a) what are the x- and y-
components of the dog's velocity?
(b) What are the magnitude and
direction of the dog's velocity? (c)
Sketch the velocity vectors at t1 and
?t2. How do these two vectors differ
