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.
average speed = distance traveled/time of trip
change in velocity = vf - vi
average acceleration = Δv/Δt
3. I understand how to calculate the change in velocity and average speed and acceleration, however the problem throws me off b/c of the way it's set up..I am confused at where to begin solving this problem b/c of the radius and the whole arc thing. If someone could please help me get started I would appreciate it. Thanks.
