1. The problem statement, all variables and given/known data a 3000 kg truck traveling at a speed of 4.0 m/s makes a 90 degree turn in a time of 5.0 s and emerges from this turn with a speed of 7.0 m/s. what is the magnitude of the average resultant force on the truck during this turn? 2. Relevant equations 3. The attempt at a solution I think this might be a centripetal force problem but the change in velocities is messing me up.
