- A race car enters the circular portion of a track that has a radius of 65 m. Disregard the 70 m in the picture. When the car enters the curve at point P, it is traveling with a speed of 120 km/h that is increasing at 5 m/s^2 . Three seconds later, determine the x and y components of velocity and acceleration of the car. I'm having trouble getting the correct y component of acceleration. all the other answers are correct. thank you!arrow_forwardFigure: 06_P041 Copyright 2013 Pearson Education, publishing a Prentice Hall 2.
