Problem 109GP
You push a box along the floor against a constant force of friction. When you push with a horizontal force of 75 N, the acceleration of the box is 0.50 m/s2; when you increase the force to 81 N, the acceleration is 0.75 m/s2. Find (a) the mass of the box and (b) the coefficient of kinetic friction between the box and the floor.

Problem 109GP
You push a box along the floor against a constant force of friction. When you push with a horizontal force of 75 N, the acceleration of the box is 0.50 m/s2; when you increase the force to 81 N, the acceleration is 0.75 m/s2. Find (a) the mass of the box and (b) the coefficient of kinetic friction between the box and the floor.
ANSWER:
Step 1 of 5
Here we have to calculate the mass of the box which is being pulled by applying a force against the friction force. Also, we need to calculate the coefficient of kinetic friction between the floor and box.
Given data,
Case I,
Applied force,
Acceleration,
Case II,
Applied force,
Acceleration,
To find,
- Mass of the box,
- Coefficient of kinetic friction,
