Two blocks, connected together by a thin but strong cord, are
placed on a ramp as shown in the figure. The angle of the ramp is
?=30 degrees , the masses of the blocks are mA = 1.00kg and mB =
2.00kg, and the coefficient of static and kinetic friction between
boxes and ramp are µs = 0.500 and µk = 0.200. The gravitational
acceleration is 9.8m/s2 . The mass of the cord is negligible. The
cord does not stretch...

Two blocks, A and B, are initially held together by a string as
shown in the figure; the mass of block A is of 2 kg and the mass of
block B is 4 kg. The massless spring in-between the two blocks has
a spring constant of k = 655 N/m and is initially compressed by 45
cm. The two blocks are initially moving together with a speed of 1
m/s. When the string is cut (i.e., when the blocks...

Two blocks A and B of equal masses are release from an inclined plane of inclination 45° at t=o. Both the blocks are initially at rest. The coefficient of kinetic friction between the block A and the inclined plane is 0.2 while it is 0.3 for block B. Initially the block A is sqrt2 m behind the block B. When and where their front faces will come in a line.
