A 200 kg box is pulled by 2600 N of force at an angle of 30 degree with horizontal line. If the friction coefficient of the box on the surface is o.4, find the acceleration of the box. If the box pushed by 20 degree using the same force, what will be the acceleration of the box?

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
