A small toy airplane is flying in the ?xy?-plane parallel to the ground. In the time interval ?t = 0 to ?t? = 1.00 s, its velocity as a function of time is given by = (1.20 m/s2)?tî? + [ 12.0 m/s ? (2.00 m/s2)?t?]?j?. At what value of ?t? is the velocity of the plane perpendicular to its acceleration?
