Question

A force of 24N produces an acceleration of 3m/s2 on a body of mass m1 and an acceleration of 2m/s2 on a body of mass m2. What acceleration does it produce when applied on a combination of the two bodies​

Answer 1

Using formula

F= M.A

m1=24/3=8kg

m2=24/2=12kg

Now if m1 and m2 are combined,

M= 20kg

F= 24N

A= 24/20= 1.2m/s²
