in animation 1 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. The magnitude of the finger applied by the finger is calculated to be 15.6N since the acceleration is 2.612. 1.a the force...
