A force F applied to an object of mass m1 produces an acceleration of 3.00 m /s2

Question

A force F applied to an object of mass m1 produces an acceleration of 3.00 m /s2 . The same force applied to a second object of mass m2 produces an acceleration of 1.00 m/s2. (a) What is the value of the ratio m1/m2? (b) If m1 and m2 are combined into one object, find its acceleration under the action of the force F.

Explanation / Answer

from newtons second law f = ma

f1 = m1a = m1*3

f2 = m2*a = m2*1

here f1 = f2

3m1 = m2

m1/m2 = 1/3

b) f = ma

here m = m1+m2

a = f/(m1+m2)
