Question

Consider a box sliding down horizontally across a straight line. Which of the following factors affects the amount of work done against friction in this situation?
A. Speed of the box
B. Time taken to move the box
C. Distance the box is moved
D. Direction of the box is moved​

Answer 1

Answer:

uhhh speed of box??? I think

Answer 2

The factor affecting the amount of work done against friction is the distance traveled by the box.

The work done against friction is energy dissipated in reducing frictional force along the horizontal surface.

The magnitude of the work done in reducing the frictional force along the horizontal surface is given as;

W = μFd

where;

• μ is the coefficient of friction
• F is applied horizontal force
• d is the horizontal distance traveled by the box

Thus, we can conclude that the factor affecting the amount of work done against friction is the distance traveled by the box.
