... try it and see.I am unsure how to attempt this. Do I need to know the static and moving coefficients of friction?
If you knew the kinetic coeff. of friction you could apportion part of the 20N force to overcoming friction and the rest (if any) to accelerating the box.radaballer said:Homework Statement

Without the coefficient of friction, the acceleration is not knowable.jove8414 said:From the problem you can tell what is the initial velocity and the acceleration, right?
The speed of the box is determined by dividing the distance between the starting point and the wall by the time it takes for the box to reach the wall.
Yes, the weight of the box can affect the time it takes to reach the wall. A heavier box will require more force to move it, and therefore may take longer to reach the wall.
The time it takes for the box to reach the wall can be affected by various factors such as the surface the box is moving on, the force applied to the box, and any obstacles in its path.
Yes, the exact time it will take for the box to reach the wall can be calculated by using the equation t = d/v, where t is time, d is distance, and v is velocity (speed).
Yes, the time it takes for the box to reach the wall can be changed by altering the variables in the equation t = d/v. For example, increasing the speed or decreasing the distance will result in a shorter time for the box to reach the wall.
