Question

a plane starting from rest is accerlated to its take off speed of 80 m/s in 6 seconds. Whats is its rate of accerleration?

Answer 1

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
