A satellite in outer space is moving at a constant velocity

Question

Solve the all parts of given question:

Question: A satellite in outer space is moving at a constant velocity of 21.2 m/s in the +y direction when one of its onboard thruster turns on, causing an acceleration of 0.300 m/s² in the +x direction. The acceleration lasts for 49.0 s, at which point the thruster turns off.

Part A: What is the magnitude of the satellite's velocity when the thruster turns off?

Part B: What is the direction of the satellite's velocity when the thruster turns off?

I need help to solve the above question and give your answer as an angle measured counterclockwise from the +x-axis.
