Answer:
Yes . Frictions was not included for the calculation for acceleration .
Explanation:
This is because we're considering the weight of an object which isn't acceleration i:e frictionless.
If friction is included, the equation for acceleration becomes.
F= ma,(Newton second law of motion)
where F=frictional force , m =mass of the object and a=acceleration..
So therefore, a = F/m.
No. What most people call 'terminal velocity' is the speed of the falling
object when the downward force of gravity is equal to the upward force
of air resistance. At that speed, the vertical forces on the object are
balanced, so it stops accelerating, and falls at a constant speed.
If there were no atmosphere, there would be no upward force due to
air resistance. The falling object would continue to accelerate all the
way down until it went 'splat'.
This is exactly the situation for meteoroids or asteroids falling onto the Moon.

Answer:
F = 1250000 N
Explanation:
If you have 50,000 S, by 25 M. It would be calculated to 1,250,000 N.
