A car accelerates uniformly from rest, and is initially pointed north. It then travels in a quarter circle taking 10.0 s and reaching a final speed of 30.0 in/s traveling due east. (a) What is the radius of its path At 5.0 s from the start, determine (b) the car's tangential acceleration (including direction), (c) the car's centripetal acceleration (including direction), and (d) the car's velocity.
