1. An airplane is flying with a velocity of (150, 0) m/s. It is accelerated at 8.92 m/s2 in the x direction, and accelerated in negative y direction at 1.21 m/s2. What is the airplane's velocity at t = 3.6 s? 2. My textbook says this is a relevant equation: average acceleration = change in velocity/change in time. ax=change in velocityx/change in time ay=change in velocityy/change in time. Where vx and vy are the components of velocity. 3. So, I plugged the knows (time and acceleration) into the equations and got 32.1 m/s and 4.4 m/s. But I knew it was wrong because why would they give (150, 0) m/s? How do I solve this problem?
