A block of mass m1- 8.2 kg is at rest on a plane that makes an angle of 9 30° above the horizontal. The coefficient of kinetic friction between the block and the plane is k-0.100. The block is attached to a second block of mass m2- 17.8 kg that hangs freely by a string that passes over a frictionless, massless pulley (see the Figure). Calculate the speed when the second block has fallen 9.7 m. (Your result must contain...
A block (block 5) of mass m5 = 2.3 kg hangs from the end of a (massless) string which runs over a (massless frictionless) pulley. The other end of the string is connected to another block (block 4) of mass m4 = 6.1 kg on a surface inclined at an angle of θ = 27o above the horizontal.
