A car makes a quarter turn around a circular track of radius 80 m in 6 seconds. What is the centripetal acceleration assuming uniform circular motion.
Must not only give answer, but also method on how it was solved.
Also, When is the tension in an elevator the greatest: (1) constant velocity, (2) slowing down on the way up, (3) slowing down on the way down.
Again, it's not enough to give the answer, but also the reason behind the answer.
