Block A on the left has mass $1\mathrm{.}00$ kg$.$ Block B on the right has mass $3\mathrm{.}00$ kg$.$ The blocks are forced together, compressing the spring. Then the system is released from rest on a level, frictionless surface. After the blocks are released, how does p$\_\{$A$\}($the magnitude of momentum of block A$)$ compare to p$\_\{$B$\}($the magnitude of momentum of block B$)?$A$.$ p$\_\{$A$\}=$ p$\_\{$B$\}/9$B$.$ p$\_\{$A$\}=$ p$\_\{$B$\}/3$C$.$ p$\_\{$A$\}=$ p$\_\{$B$\}$D$.$ p$\_\{$A$\}=3$p$\_\{$B$\}.$ p$\_\{$A$\}=9$p$\_\{$B$\}$m$\_\{$A$\}=1$kgSm$\_\{$B$\}=3$kg
