A horizontal force of 40 N acting on a block on a frictionless level surface produces an acceleration of 2.5 m/s2. A second block, with a mass of 4.0 kg, is dropped onto the first. What is the magnitude of the acceleration of the combination of blocks if the same force continues to act? (Assume that the second block does not slide on the first block.)

A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg.
A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right.Part (a) Solve numerically for the magnitude of the normal force, FN in newtons, that acts on the block if θ = 30°. Part (b) Solve...

im A rope at an angle θ with the horizontal is pulled with a force UF. It pulls, in turn, two blocks, the bottom with mass M and the top with mass m. The coefficients of friction are p, between the top and bottom block (assume that they do not slide for the given force ) and pu between the bottom block and the table. Remember to show (and possibly evaluate) all forces acting on both blocks, including internal forces...
