Question Number 10760 by Saham last updated on 24/Feb/17

A block of mass 2.0kg resting on a smooth horizontal plane is acted  upon simultaneously by two forces 10N due north and 10N due east.  The magnitude of the acceleration produce by the force on the block.

$$\mathrm{A}\:\mathrm{block}\:\mathrm{of}\:\mathrm{mass}\:\mathrm{2}.\mathrm{0kg}\:\mathrm{resting}\:\mathrm{on}\:\mathrm{a}\:\mathrm{smooth}\:\mathrm{horizontal}\:\mathrm{plane}\:\mathrm{is}\:\mathrm{acted} \\ $$$$\mathrm{upon}\:\mathrm{simultaneously}\:\mathrm{by}\:\mathrm{two}\:\mathrm{forces}\:\mathrm{10N}\:\mathrm{due}\:\mathrm{north}\:\mathrm{and}\:\mathrm{10N}\:\mathrm{due}\:\mathrm{east}. \\ $$$$\mathrm{The}\:\mathrm{magnitude}\:\mathrm{of}\:\mathrm{the}\:\mathrm{acceleration}\:\mathrm{produce}\:\mathrm{by}\:\mathrm{the}\:\mathrm{force}\:\mathrm{on}\:\mathrm{the}\:\mathrm{block}. \\ $$

total force F=(√(10^2 +10^2 ))=14.1 N  a=(F/m)=((14.1)/2)=7.05 m/s^2

$${total}\:{force}\:{F}=\sqrt{\mathrm{10}^{\mathrm{2}} +\mathrm{10}^{\mathrm{2}} }=\mathrm{14}.\mathrm{1}\:{N} \\ $$$${a}=\frac{{F}}{{m}}=\frac{\mathrm{14}.\mathrm{1}}{\mathrm{2}}=\mathrm{7}.\mathrm{05}\:{m}/{s}^{\mathrm{2}} \\ $$
