Question

A post produces an acceleration a1 on a body at the same force produces acceleration a2 on a body be find the solution if the same force acts on combination of a and b

Answer 1

f=m*a
F1=f2
F1=M*A1
F2=m*A²
F3=(m1+m2)A3
(m1+m2)A3=m1*A1
A3=m1*A1/(m1+m2)

Answer 2

. The problem statement, all variables and given/known data A force F to an object m1 produces an acceleration of 3m/s^2. The same force is applied to a second object of mass m2 produces an acceleration of 1.00m/s^2 a.) value ratio of m1/m2 b.) If m1 and m2 are combined into 1 object, what is the acceleration under the action of force
