Answer:

Explanation:

Formula for acceleration:

a = (Final Velocity - Initial Velocity)/ time

a = (Vf - Vo)/t

Given:

Vo = 50.0 m/s

Vf = 20.0 m/s

t = 6.0 s

Solution:

a = (Vf - Vo)/t

a = (20.0 m/s - 50.0 m/s)/6.0 s

a = (-30.0 m)/ 6.0 s • s

a = -5 m/s² ANSWER

NEGATIVE ACCELERATION means that there is a decceleration that took place.
