1.	A 500 kg horse pulls a cart of mass 1500 kg along a level road with an acceleration of 1 m//s^(2). If coefficient of sliding friction is 0.2, then force exerted by the earth on horse is
Answer» 3000N 4000N 5000 N 6000N Solution :Force of friction `F_(1)=MU(m_(1)+m_(2))g` force producing ACCELERATION `F_(2)=(m_(1)+m_(2))a` Total foce APPLIED by the horse `=F_(1)+F_(2)`
