Lorslaris A small toy airplane is flying in the xy-plane parallel to the ground. In the time interval t=0 to t=10.0 s, its velocity as a function of time is given by ū = (1.50m/s?)tî + [11.0m/s – (2.00 m/s?)t] . Part A At what value of t is the velocity of the plane perpendicular to its acceleration? Express your answer to three significant figures and include the appropriate units.
