A squirrel has x- and y-coordinates (1.1 m, 3.4 m) at time t1 = 0 and coordinates (5.3 m, - 0.5 m) at time t2 = 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.

Solution 1E The components of average velocity is found by using average velocity formula avg.velocity = (x x )/(t t ) 2 1 2 1 In this case, v x (5.3 1.1)/(3.0) = 1.4 m/s. v y ( 0.5 3.4)/(3.0) = 1.3 m/s. v = v 2 + v 2 = 1.91 m/s. x y direction:tan = v yv x 45 ,below the positive x axis.
