(adsbygoogle = window.adsbygoogle || []).push({}); 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.

a_{x}=change in velocity_{x}/change in time

a_{y}=change in velocity_{y}/change in time.

Where v_{x}and v_{y}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?
