Homework Help: Physics

Posted by Erica on Wednesday, February 1, 2012 at 10:50am.

A car's initial velocity of 13.5 m/s accelerates at a rate of 1.9 m/s^2 for 6.2 s. Then, it accelerates at a rate of -1.2 m/s^2 until it stops.

1) What is the car's maximum speed?
2) What is the total time from the start of the first acceleration until the car is stopped?
3) Find the total distance that the car traveled.

Please include all steps used in the calculations if possible. Thank you!
