1.	Two masses m_(1) = 4.8 kg and m_(2) = 5 kg tied to a string are hanging over a light frictionless pully. What is the acceleration of masses when they are free to move ?
Answer» 0.2 `m//s^(2)` 9.8 `m//s^(2)` 5 `m//s^(2)` 4.8 `m//s^(2)` SOLUTION :Supposethe accelerationof compositesystemis a `m_(2) g - T =m_(2)a ` and Addingthesetwoequations `(m_(2)-m_(1)) g =(m_(1) =m_(2)) a` `a= ((m_(2) - m_(1))/(m_(1) + m_(2))) g ` `=((5-4.8)/( 5+4.8)) 9.8` `=(0.2)/(9.8) xx 9.8` `a= 0.2 m//s^(2)`
