Question

When 15 N force is applied on a body of mass m₁ acceleration produced is 3 m/s². Now it is tied with a body of mass m₂ and same force is applied on a composite body and acceleration produced is 2 m/s². Find mass of both the bodies.

Answer 1

Answer:

m1=5kg

m2=2.5kg

Explanation:

case 1

Mass×Acceleration =Force

m1=15/3=5kg

case 2

M1+M2×Acceleration =Force

5+m2=15/2=7.5kg

m2=2.5kg

Check

7.5×2=15N
