Question
. A squirrel has x- and y-coordinates (1.1 m, 3.4 m) at time t, = 0 and coordinates (5.3 m,
-0.5 m) at t, = 3.0 s. For this time interval, find (a) the components of the average
velocity, and (b) the magnitude and direction of the average velocity.
Transcribed Image Text:. A squirrel has x- and y-coordinates (1.1 m, 3.4 m) at time t, = 0 and coordinates (5.3 m, -0.5 m) at t, = 3.0 s. For this time interval, find (a) the components of the average velocity, and (b) the magnitude and direction of the average velocity.
A dog running in an open field has components of velocity vỵ = 2.6 m/s and v, =
-1.8 m/s at t, = 10.0 s. For the time interval from t, = 10.0 s to t, = 20.0 s, the
average acceleration of the dog has magnitude 0.45 m/s² and direction 31.0° measured
from the +x-axis toward the +y-axis. At t, = 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 t, and t,. How do these two vectors differ?
