Blocks of 4 kg ( $A$ ) and 2 kg ( $B$ ) are joined by a spring of 1200 N/m on a smooth plane, spring undeformed. $A$ gets 2 m/s and $B$ gets 8 m/s in the same direction. Select the correct statement(s).

Options:(select one or more)

Answer:

B, C, D

Solution:

$v_{c m} = 4$ m/s, relative speed 6, $μ = \frac{4}{3}$ , $ω = 30$ . $x_{ma x} = 6/30 = 20$ cm at common velocity 4 m/s. $3 T /4 = \frac{3}{4} \cdot \frac{2 π}{30} = π /10$ s.
