Help please :) 1. The problem statement, all variables and given/known data A Car with a velocity of 25m/s[E] changes its velocity to 25m/s in 15s. Calc. the car's average acceleration. 2. Relevant equations Aav= Vf - Vi / T 3. The attempt at a solution I know that the angle is = to 45 degrees S of W since it's a right angle triangle and two sides are equal, therefore, 90 + 45 + 45 = 180.
