suppose that Andrew is running down the field at 8 yards per second and then cuts right running 6 yards per second. He executes this maneuver in 0.5 seconds. Calculate his acceleration

acceleration= change velocity/time
= (6yds/sec right8yds/sec ahead )/.5
From experience, this is a 345 triangle, so the answer is 10yards/sec^2 in a direction of the angle whose tangent is 3/4 to the right.
You must have a coach for a teacher. Using American English units such as yards is not good use for preparing you for college, you really need to be learning the SI system of units.
