A 45.0-kg crate of tools rests on a horizontal floor. You exert a gradually increasinghorizontal push on it and observe that the crate just begins to move when your forceexceeds 313 N. After that you must reduce your push to 208 N to keep it moving at asteady 25.0 cm/s. (a) What are the coefficients of static and kinetic friction between thecrate and the floor. (b) what push must you exert to give it an acceleration of 1.10 m/s2 ?

Two boxes are at rest on a smooth, horizontal surface. The boxesare in contact with one another. If box 1 is pushed with a forceof magnitude F = 12.00 N, the contact force between the boxesis 8.50 N; if, instead, box 2 is pushed with the force F, the contactforce is 12.00 N - 8.50 N = 3.50 N. In either case, the boxes movetogether with an acceleration of 1.70 m>s2. What is the mass of(a) box 1 and (b) box 2?
