Question

. A 15 kg box is pulled by a force of 75 N across a floor. If the box accelerates at 3.0 m/s, what is the
coefficient of friction between the box and the floor?​

Answer 1

The maximum value of the static friction possible=μ

s

​

mg=0.5×100×10=500N>344N

Thus the static friction would adjust to 344N and would not allow the box to move at all.
