A force F applied to an object of mass m1 produces an acceleration of 3.20 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 2.00 m/s2.
(a) What is the value of the ratio m1/m2?
(b) If m1 and m2 are combined, find their acceleration under the action of the force F.
m1/m2 * a1/a2=1
