A force of 5 N gives a mass M₁ an acceleration equal to 8 ~m / s ^2 and M₂ an acceleration equal to 24 ~m / s ^2 . What is the acceleration, if both masses are tied together ?
Options
- A16 ~m / s ^2
- B6 ~m / s ^2
- C12 ~m / s ^2
- D4 ~m / s ^2
Correct answer
B. 6 ~m / s ^2
Step-by-step solution
Mass M₁= 5 8 ~kg , Mass M₂= 5 24 ~kg Total maks =M₁+M₂= 5 8 + 5 24 = 20 24 ~kg Therefore, total acceleration in two masses aligned & = F M₁+M₂ = 5 20 / 24 & = 5 24 20 =6 ~ms ⁻² aligned
