A dog running in an open field has components of velocity v, Ask an Expert

Academics

A dog running in an open field has components of velocity v, = 2.6 m/s and Vy = -1.8 m/s at t, = 10.0 s. For the time interval from f, = 10.0 s to 12 = 20.0 s, the average acceleration of the dog has magnitude 0.45 m/s2 and direction 31.00 measured from the + x-axis toward the +y-axis. At f2 = 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?
