1.An airplane is flying with velocity (152, 0) m/s. It is accelerated in the x direction by its propeller at 8.92 m/s2 and in the negative y direction by a strong downdraft at 1.21 m/s2. What is the airplane's velocity after 4.30 seconds?
2.An electron starts at rest. Gravity accelerates the electron in the negative y direction at 9.80 m/s2 while an electric field accelerates it in the positive x direction at 3.80×106 m/s2. Find its velocity 2.45 s after it starts to move.
