A force of `10 N` gives a mass `m_(1)` an acceleration of `10m//s^(2)` and a mass `m_(2)` an acceleration of `20m//s^(2)` What acceleration would it give if both the masses are tid together ?

Answer» Correct Answer - `6.66 m//s^(2)`
Here, `m_(1) = (F)/(a_(1)) = (10)/(10) = 1kg`
`m_(2) = (F)/(a_(2)) = (10)/(20) = 0.5kg`
If a is the acceleration in the combination of masses, then
`a= (F)/((m_(1) +m_(2))) = (10)/(1 + 0.5) = 6.66 m//s^(2)` .
