Question

6. A car is traveling at 50m/s when it begins to slow down to

20m/s. This took the car 5s to slow down. Calculate the
acceleration. *

Answer 1

-5

Step-by-step explanation:

Answer 2

-6 m/s²

Step-by-step explanation:

Given:

v₀ = 50 m/s

v = 20 m/s

t = 5 s

Find: a

v = at + v₀

20 m/s = a (5 s) + 50 m/s

a = -6 m/s²
