Hello, I've got a problem I've got stuck with. Anyone who can help me solve this?
A 4kg block hangs by a light string that passes over a massless, frictionless pulley and is connected to a 6kg blovk that rests on a shelf. The coeff of kinetic friction is 0,2. The 6kg block is pushed against a spring, compressing it 30cm. The spring has a force constant of 180nm.
How do i fins the speed och the 6kg block after its released and the 4kg block has fallen 40cm?
Anyone out there who can help me?
