Question

Bina is pushing a box filled with winter clothing into the closet. The box has a mass of 11.4 kg, and when she pushes with a force of 25.9 N, it accelerates at a rate of 0.84m/s^2 . Based on these values, what is the coefficient of friction between the box and the floor of the closet?

Answer 1

Step-by-step explanation:

ASSUMING the push is HORIZONTAL

F = ma

F - μN = ma

F - μmg = ma

F - ma = μmg

μ = (F - ma) / mg

μ = (25.9 - 11.4(0.84) / (11.4(9.81)

μ = 0.14596634...

μ = 0.15
