Two blocks, with masses m1 = 2.5 kg and m2 = 14 kg, approach each other along a horizontal, frictionless track. The initial velocities of the blocks are v1 = 1.20 m/s to the right and v2 = 0.34 m/s to the left. The two blocks then collide and stick together.

As shown in the figure, blocks of masses m1 = 268.9 g and m2 = 598.5 g are attached by a massless string over a frictionless and massless pulley. The coefficients of static and kinetic friction between the block and inclined plane are 0.250 and 0.123, respectively. The angle of the incline is θ = 27.1∘, and the blocks are at rest initially. What is the acceleration of the blocks? [Answer with a negative number if m2 moves downward, and a positive number if it moves upward. ] Submit Answer Incorrect. Tries 1 /99 Previous Tries

A light cord is passed around a frictionless pulley and connected to the two masses as shown, with m2 pulled by a constant horizontal force, F. The coefficient of kinetic friction between m1 and m2 is the same as that between m2 and the horizontal surface. Find an expression for μk (in terms on F, m1, m2 and any constants needed) if the blocks are to move with constant speed.
