1. The problem statement, all variables and given/known data A 2200 kg truck traveling north at 31 km/h turns east and accelerates to 50 km/h. (a) What is the magnitude of the change in the linear momentum of the truck? (b) What is the direction of the change in the linear momentum of the truck (in degrees)? 2. Relevant equations p=mv 3. The attempt at a solution I found the momentum for each speed and then subtracted the smaller one from the larger one, but it was incorrect. What am I doing wrong? And for part (b) I have no clue.
