Question

A car is traveling at a constant velocity of 19 m/s when the driver puts on the brakes to accelerate it at - 1.4 m/s ^ 2 until stopped. How long in s) did it take the car to stop?

answer must be a number only !

Answer 1

14 s

Step-by-step explanation:

Given:

v₀ = 19 m/s

a = -1.4 m/s²

v = 0 m/s

Find: t

v = at + v₀

(0 m/s) = (-1.4 m/s²) t + (19 m/s)

t ≈ 14 s
