A0.300-kg block along a horizontal track has a speed of 1.20 m/s immediately before colliding with a light spring of force constant 4.40 n/m located at the end of the track. (a) what is the spring's maximum compression if the track is frictionless?

x = 0.3 m

Explanation:

mass of block (Mb) = 0.3 kg

velocity of the block (v) = 1.2 m/s

force constant of the spring (k) = 4.4 N/m

from the conservation of energy

the initial kinetic energy of the block = the final spring energy

m

x = v x

x = 1.2 x

x = 0.3 m

0.19 m/s and 0.45 m/s
