A 1 kg block on a spring of constant 400 N/m is compressed 0.5 m. A 3 kg block rests at 0.3 m from the equilibrium position on the other side. The 1 kg block strikes it and they stick. Select the correct statement(s).

Options:(select one or more)

Answer:

A, C

Solution:

$ω = 20$ , $v = 20 0.25 - 0.09 = 8$ m/s. $1 (8) = 4 v_{f}$ gives $v_{f} = 2$ m/s. $ω_{f}^{2} = 400/4 = 100$ , $A_{f}^{2} = 0.09 + 0.04 = 0.13$ , $A_{f} = 0.36$ m.
