  A car is traveling due north at 24.0 m/s. (a) Find the velocity of the car after5.50 s if its acceleration is 1.60m/s2 due north

(b) Find the velocity of the car after 5.50 s if its acceleration is instead 1.95m/s2 due south. This is question is not on the textbook. Thank you so much!

(b) Find the velocity of the car after 5.50 s if its acceleration is instead 1.95m/s2 due south.

Explanation / Answer

1. vfinal = vinitial +at v= 24.0 m/s + 1.60 m / s2 (5.50 s) v = 32.8 m/s 2. vfinal = vinitial +at v = 24. 0 m/s + -1.95 m/s2 (5.50 s) v = 13.275 m/s As the car is accelerating south and the original accelerate wasnorth, the acceleration must be represented as the opposite of theoriginal velocity. Thus the 1.95 is negative in thisequation.
