two boxes one of mass 20kg and the other of   mass 30kg sre sliding down on a frictionless  inclined plane that makes an angle of 25^0  with the   horizontal. find their redpective accelerstions.

accelaration (if frictionless)  =gsinθ  20sin25°=8.42365(m/s^2 )  30sin25°=12.678548(m/s^2 )
$${accelaration}\:\left({if}\:{frictionless}\right) \\ $$$$={gsin}\theta \\ $$$$\mathrm{20}{sin}\mathrm{25}°=\mathrm{8}.\mathrm{42365}\frac{{m}}{{s}^{\mathrm{2}} } \\ $$$$\mathrm{30}{sin}\mathrm{25}°=\mathrm{12}.\mathrm{678548}\frac{{m}}{{s}^{\mathrm{2}} } \\ $$
