A Spaceship Is Observed Traveling in the Positive X Direction

A spaceship is observed traveling in the positive x direction with a speed of 150 m/s when it begins accelerating at a constant rate. The spaceship is observed 25 s later traveling with an instantaneous velocity of 1500 m/s at an angle of 55° above the +x axis.
-What was the magnitude of the acceleration of the spaceship during the 25 seconds?

A) 1.5 m/s²
B) 7.3 m/s²
C) 28 m/s²
D) 48 m/s²
E) 57 m/s²
