For instant shown, A has a speed of 100 km/hr, which increases at 8 km/hr per second. Car B also has a speed of 100 km/hr which is decreasing at 8 km/hr. Find the acceleration that Car B appears to have to an observer in Car A.What is your main equation? Are we finding aB/Aor aA/B?Relative motionABAB/aaaaaa+=What is aA? What is aB? Is it just -2.22 m/s2?No, it has a tangential and a normal component – what is an?Just v2/ρBSolve for aB/ADoes it make sense?If I am in A, it appears that B is accelerating to the left (+j in their coordinate
