Question

A force of 10N produce and acceleration of 2ms in a body of mass M1 and 5ms in a body of mass M2. What will be the acceleration produced by the same force when both the bodies are tied together​

Answer 1

force acts on 1st body: 10N

acceleration produces: 5ms^-2

F =ma

10= m X 5

so, mass(m1) of the body will be 2kg

force acts on 2nd body :10N

F= ma

10= m X 2

mass (m2) of the body will be 5kg

if they tied together,

F = (m1 + m2) x a

10 = (5+2)X a

a= 10/7

= 1.42
