Answer to Question #2979 in Mechanics | Relativity for Harpal Brar

Question

A 190 kg block is released at a 5.2 m height
as shown. The track is frictionless except for
a portion of length 6.6 m. The block travels
down the track, hits a spring of force constant
1980 N/m. The coefficient of kinetic friction
between surface and block over the 6.6 m
track length is 0.58 .
Determine the compression of the spring x
from its equilibrium position before coming to
rest momentarily. The acceleration of gravity
is 9.8 m/s2 .
Answer in units of m.
