The Change in velocity and direction.

    1. The problem statement, all variables and given/known data
    What is the acceleration of a bullet that was shot at 40.m/s in the horizontal and then changed to a velocity of 44.5m/s at 26.1* below the horizontal in a time of 2.0 seconds.

    2. Relevant equations

    vf-vi= delta v a= delta v / time

    3. The attempt at a solution

    I have tried to solve using head to tail diagram and i ended up 41m/s2. I am not entirely sure of this answer, and I have a test next morning on this.

    That's not correct. Show how you got that result.
