Question

A car is initially traveling due north at 24.0 m/s.
A.) find the velocity of the car after 4.00 seconds if it's acceleration is 1.60 m/s2 due north.
B.) find the velocity of the car after 4.00 seconds if it's acceleration is instead 1.95 m/s2 due south.

Answer 1

v = Vi + a t

v = 24 + 1.6(4)

v = 24 - 1.95(4)

Answer 2

30.4 m

16.2 s
