imdiate Help needed :( 1. The problem statement, all variables and given/known data A 2000 kg truck traveling at a speed of 6 m/s makes a 90 turn in a time of 4 s and emerges from this turn with a speed of 4 m/s. What is the magnitude of the average resultant force in KN on the truck during this turn? 2. Relevant equations F avr. = Pf - Pi / t 3. The attempt at a solution Pf = m Vf = 2000 * 4 = 8000 Pi = m Vi = 2000 * 6 = 12000 Pf - Pi = - 4000 and F avr. in KN = -1 Is that Right ???
