Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs vertically and one mass slides on a $30\mathrm{.}0$ degree frictionless incline.

Clear

The vertically hanging mass is $4\mathrm{.}00$ kg and the mass on the incline is $6\mathrm{.}00$ kg$.$ The acceleration of the $4\mathrm{.}00$ kg mass is

$0\mathrm{.}980$ m$/$s down.
