Two objects, in contact with each other, are being pushed across a table. The masses are 113g and 139g. Friction is negligible. The applied horizontal force of magnitude 0.0538N is exerted on the more massive object. Determine the acceleration of the two object system and the magnitude of the force exerted by each of the two objects on the other.
Fnet = m*a
The Attempt at a Solution
To find acceleration I use f=ma, with f being the applied horizontal force and m being the total mass:
a= 0.0538/ (0.113+0.139)
Now I'm confused about how the forces are acting between the two objects in the system. How is this calculated?
