Q3:

An aircraft is flying eastward, accelerating at 12 m/s². The aircraft is also descending vertically with an acceleration of 9 m/s². Before accelerating, the eastward velocity of the aircraft was 250 m/s and its vertical speed was 10 m/s. What is the speed of the aircraft after 10 seconds of acceleration? Answer to the nearest meter per second.
