1. The problem statement, all variables and given/known data At t = 0, an automobile traveling north begins to make a turn. It follows one-quarter of the arc of a circle of radius 10.5 m until, at t = 1.42 s, it is traveling east. The car does not alter its speed during the turn. Find the car's speed. Find the change in it's velocity during the turn Find it's average acceleration during the turn 2. Relevant equations Speed- m/s Change of velocity 3. The attempt at a solution When I first read this problem, the first thing I did was draw a circle. With the circle, I made a 1/4th arc and separated into segments with 10.5 m. Then I outlined the whole arc's time would be 1.42 seconds. So I added the 4 segments and divided them by 1.42 to get the speed. Didn't work. The other questions fall into getting this one. Help would be appreciated!
