Answer:
a = 13.3 m/s^2
Step-by-step explanation:
Comment
This is an application question for the formula a = (vf - vi)/t
Givens
t = 6 seconds (this is the given time in the formula)
vi = 0 The plane starts from rest
vf = 80m/s This is its final speed after 6 seconds
a = ?
Formula
a = (vf - vi) /t
Solution
a = (vf - vi) /t Substitute the givens into the formula
a = (80 - 0)/6 Drop the 0 and divide.
a = 80/6
a = 13.3 m/s^2
