A 55-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.30. A horizontal 140-N force is applied to the box. What is the friction force on the box?

Step 1
This is done by multiplying the mass of the box by the acceleration due to gravity (9.8 m/s^2). Force of gravity = mass * gravity = 55 kg * 9.8 m/s^2 = 539 N Show more…

A 55-kg box rests on a horizontal surface. The coefficient of static friction between the box the surface is 0.30, and the coefficient of kinetic friction is 0.20. What horizontal force must be applied to the box to cause it to start sliding along the surface?

A $50-\mathrm{kg}$ box rests on the floor. The coefficients of static and kinetic friction between the bottom of the box and the floor are 0.70 and 0.50 , respectively. (a) What is the minimum force a person needs to exert on the box to start it sliding? (b) After the box starts sliding, the person continues to push it, exerting the same force. What is the acceleration of the box?
