1.	Two masses of 3 and 4 kg are connected at the two ends of a light inextensible that passes over a frictionless pulley. Find the acceleration of the masses and the tension in the string, when the masses are released.
Answer» SOLUTION :(i) `a=((M_(1)-M_(2))g)/(M_(1)+M_(2))=((4-3)9.8)/(4+3)=1.4 ms^(-1)` (ii) `T=(2M_(1)M_(2)g)/(M_(1)+M_(2))=(2(4)(3)(9.8))/(4+3)=33.6 N`.
