The pilot of an airplane is flying 340 km/h due West relative to the air. If it encounters a wind blowing at 85 km/h, 35° North of East relative to the ground, what is the plane’s velocity relative to the ground?

Which of the following describe possible scenarios? a) an object has zero instantaneous velocity and non-zero acceleration. b) an object has negative acceleration and is speeding up. c) an object has positive acceleration and constant velocity. d) an object has positive velocity and zero acceleration. e) an object has increasing positive position and negative velocity. f) an object has decreasing positive position and negative acceleration.
