I am guessing by what I had it is a plz don't quote me on that I could be wrong
The force of friction is zero.
Using F = m a = the force needed is 6 N which means no friction can be acting.
Answer:
the higher the value of the coefficient of friction the MORE the resistance to sliding .
Answer:
The total distance at 7 s is:

Explanation:
<u>Distance due to the force</u>
We can use second Newton's law to find the acceleration.


Now, using the kinematic equation we will find the distance during this interval of time. Let's recall that the initial velocity is zero.



In the second part of the motion, the object moves at a constant velocity, as long as there is no friction between the object and the floor.
First, we need to find the final velocity of the first interval

So the second distance will be:

Therefore, the total distance is:
