Question
A block of mass m = 1.2Kg is on a plane
%3D
inclined at 30 degrees for which uc = 0.11.
The block is connected to a spring of
constant K = 3.2 N / m, by a rope passing,
without slipping, by a pulley. The pulley is
a disc of 0.8Kg and 0.14m radius. If the
system is initially at rest and the spring
has zero elongation, what is the block
velocity modulus when the block has slid
0.25m down the inclined plane?
k=3,2 N/m
