Given
m: mass
m = 1.20 kg
μ: kinetic friction
μ = 0.25
vi: speed contact light spring
vi = 3.40 m/s
k: spring costant force
k = 50 N/m
Procedure
a) distance of compression
energy balance equation
using the quadratic formula we get,
(b) find the speed v, at the unstretched
energy balance equation
(c) Find the distance D where come to rest
energy balance equation
(d) What if? The object becomes attached to the end of the spring
The distance would be 0.35m
