Question

How much time does it take an airplane to accelerate from rest at a rate of 6.0 meters for a distance of 432?

A. 4.0 seconds
B. 3.0 seconds
C. 36.0 seconds
D. 72.0 seconds

Answer 1

The airplane takes 72 seconds to accelerate from rest at a rate of 6.0 meters per second.

Step-by-step explanation:

To find the time it takes for the airplane to accelerate from rest, we can use the equation:

vf = vi + at

Where vf is the final velocity, vi is the initial velocity (which is 0 m/s since the airplane starts from rest), a is the acceleration, and t is the time.

In this case, the final velocity is the given distance 432 m:

432 = 0 + 6t

Simplifying the equation, we get:

t = 432 / 6 = 72 s

Therefore, it takes the airplane 72 seconds to accelerate from rest at a rate of 6.0 meters per second.
