[2] A block with mass ma is placed on an inclined plane with slope angle α and is connected to a second hinging block with mass ma > ma by a massless cord passing over a small frictionless pulley (see figure). The coefficient of kinetic friction between mass mA and the incline is negligible. Initially the masses are at rest, with mass mA at the bottom of the incline and mass mg a height h above the table supporting the...
given: the block B with mass mb lies on a block A (mass ma), that lies on a table with no friction. between blocks A and B is there a static friction force. A light rope, goes from block A to a massless, fictionless pulley, to a hanging block C (mass mc). asked: determine the acceleration of block C when the system was initially at rest has been let go in function of the masses (abc) and g. also determine...
answer all please Problem 1. A block of mass m = 735 g is located on an incline which makes an angle of 40 with the horizontal The friction coefficient between the block and the incline is K = 0.21. The block is released and it is let slide down the incline. (a) Draw a free body diagram and identify all forces acting on the block. Find the acceleration of the block (b) If the block moves d = 0.42...
In the figure above, block A has mass mA = 25 kg and block B has mass mB = 10 kg. Both blocks move with constant acceleration a = 2 m/s2 to the right, and the coefficient of static friction between the two blocks is = 0.8. The static frictional force acting between the blocks is (A) 20 N (B) 50 N (C) 78 N (D) 196 N E) 274 N
Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...
