Question

Consider a block and a wedge. The block (mass m) has no friction when it moves on the
wedge (mass M) with angle a as shown in the figure. The wedge can slide on a horizontal
surface without friction. The block is thrown from the bottom of the wedge with both
(wedge and block) at rest. Using the Lagrange method, find the acceleration of the block
as it moves up the plane.

Mariana and Jun are both pushing on a box. Mariana pushes the box to the right and Jun pushes to the left. The box is on rollers and so is essentially frictionless with the floor, but Mariana and Jun do have friction with the floor. Jun is "winning" the pushing match and all three objects, Jun, the box, and Mariana are accelerating to the left. Consider the following forces: fm: the force of friction on Mariana f;: the force of friction on Jun FMB: the force of Mariana on the box FJB: the force of Jun on the box Which of the listed forces must be equal in magnitude and opposite in direction? Of; and FMB Mariana box Jun fm and FMB fm and fj no two of the four listed forces must be equal and opposite. FMB and FJB

A 2.0-kg block is on a perfectly smooth (frictionless) ramp that makes an angle of 30° with the horizontal. Part a (#599119) (Inclined Plane) What is the weight of the block?
A system comprised blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with Hk = 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its acceleration. A B C.
E To Two blocks, labeled D and E, are connected by an essentially massless string that runs over an essentially massless and frictionless pulley, as shown in Figure 2, above. Block E hangs straight down and is initially moving downward with a speed of 3.82 meters per second. Block D is on an inclined plane, inclined at an angle of theta = 0 = 28.6 degrees above horizontal. There is no friction between block D and most of the plane, but there is friction (with a coefficient of kinetic friction equal to 0.49) between block D and a region of length L = 0.628 meters. Block D will slide over that region (and pass it completely) before it gets to the end of the plane. Block D has a mass of 0.74 kg, while block E has a mass of 0.98 kg. The only significant forces acting on the blocks are friction acting on block D (while in contact with the region with friction), normal forces, tension forces, and gravity (with g = 9.81 m/s2). Calculate the speed of block D (in units of meters per second)…
