1. The problem statement, all variables and given/known data
2. Relevant equations
I used:
square root of: 196^2+236^2-2(196)(236)cos(45)
to get the change in velocity of 169.4
and then did 169.4/5 hours to get the average acceleration of 33.9
3. The attempt at a solution
i don't know what to do for the second one
