1. At t = 0, an automobile traveling north begins to make a turn. It follows one-quarter of the arc of a circle of radius 9.3 m until, at t = 1.60 s, it is traveling east. The car does not alter its speed during the turn.
(a) Find the car's speed.
(b) Find the change in its velocity during the turn.
(c) Find its average acceleration during the turn.
2. speed = distance traveled/time traveled
change in velocity = vf - vi
average acceleration = change in velocity/change in time
3. I am a little confused at how to begin solving this problem. I know that the first vector going north is going to be the initial velocity = vi and the second vector is going to be the final velocity = vf. the initial time = 0 sec and the finald time is = 1.60 s. Distance traveled is = 9.3 m. I am so lost at where to start. Can someone please guide me in the right direction to solving this problem?
