Answer:

t = 27 s

Explanation:

Given data:

Average acceleration = -0.50 m/s²

Time taken to reach to the 13.5 m/s = ?

Solution:

Formula:

Vf = V₀ + at

Vf = 0

V₀ = 13.5 m/s

a = -0.50 m/s²

Now we will put the values in formula.

0 = 13.5 m/s - 0.50 m/s²t

0.50 m/s²t =  13.5 m/s

t =  13.5 m/s / 0.50 m/s²

t = 27 s
