Question

If a car is traveling forward at 15 m/s, how fast will it be going in 1.2 seconds if the acceleration is

-10 m/s2?
3 m/s
27 m/s
-3 m/s
-27 m/s

Answer 1

3

Step-by-step explanation:

v = v⁰ (its original speed) + a (negative acceleration) X t² (time)

v = 15 - 10 x 1.2 = 15 - 12 = 3 (it's slowing down)
