In animation one a 1.5-kg block receives a push and in the process pushes agains

Question

In animation one a 1.5-kg block receives a push and in the process pushes against a 4.5-kg block. (position is in meters and time is in seconds). Conversely, in animation 2, the same 4.5-kg block receives the same push, now from the opposite direction, and in the process pushes against the 1.5-kg block as shown. All surfaces are frictionless.

1. Is the magnitude of the acceleration of the two-block system the same in each animation? please explain

2. What is the magnitude of the force applied by the finger in each animation? please explain how to calculate

3. In Animation 1, the force that the green block exerts on the red block points:? (multiple choice)

options:   

A to the left

B to the right

4)  In Animation 2, the force that the green block exerts on the red block points:? (multiple choice)

options:

a. to the left

b to the right

Explanation / Answer

The data provided in the question is insufficient. You have to provide either the force exerted by the finger or the acceleration of the block. Moreover, please provide the figure. Without the figure it is not possible to know which is green and which is red.
