A $40$ N force F is pushing a $3$ kg block across the floor. The $3$ kg block is pushing a $2$ kg block and the coefficient of kinetic friction between the two blocks and the floor is $0\mathrm{.}2.$

A$)(5$ pts$)$ Find the acceleration of the blocks. $q,$

B$)(2$ pts$)$ How much force is the $3$ kg block exerting on the $2$ kg block? $q,$

$F=40N$

$3$ kg

$2$ kg
