1. The problem statement, all variables and given/known data Tim is running cross country at 6.4m/s when he completes a wide angle turn and continues at 5.8m/s[w]. What is his change in velocity? 2. Relevant equations Δv=v2-v1 a2+b2=c2 3. The attempt at a solution i am not sure how i am supposed to find the change in velocity... i could just find the hypotenuse but i think that is giving me the resulting acceleration and not the actual change. but im quite sure its not as simple as just subtracting the two values either ??
