A train car of mass m = 20,000 kg is connected by a horizontal coupling to a second train car of mass M = 19,000 kg on a level, frictionless surface as shown in the figure. If a train engine applies a horizontal force of 1.05×105 N in the positive x-direction to the train car of mass M, find the acceleration of the system. (Enter your answer in m/s2. Indicate the direction with the sign of your answer.) m/s2

Three blocks are in contact with one another on a frictionless, horizontal surface as in the figure below. A horizontal force F→ is applied to m1, where m1 = 1.90 kg, m2 = 3.73 kg, m3 = 4.92 kg, and F = 20.0 N. (Take the +x-direction to be to the right. Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Find the acceleration of the blocks. (Enter your answer in m/s2. Indicate the direction with the sign of your answer.) m/s2 (b) Find the net force on each block. (Enter your answers in N. Indicate the direction with the signs of your answers.) F1,net = N F2,net = NnF3,net = N (c) Find the magnitudes of the contact forces between the blocks (in N). P12 = N P23 = N

A wedge of mass m = 40.0 kg is located on a plane that is inclined by an angle θ = 20∘ with respect to the horizontal. A force F = 307.9 N in the horizontal direction pushes on the wedge, as shown in the figure. The coefficient of kinetic friction between the wedge and the plane is 0.159. What is the acceleration of the wedge along the plane? m/s2
