Question

8. An object that is traveling 50m/s slows down with an
acceleration rate of -3.5m/s/s. This took place over a period of 4s.
What was the objects final velocity? *

Answer 1

Answer:

36 m/s

Explanation:

Given:

v₀ = 50 m/s

a = -3.5 m/s²

t = 4 s

Find: v

v = at + v₀

v = (-3.5 m/s²) (4 s) + 50 m/s

v = 36 m/s
