Forgive the probable incorrect use of words of physics, I'm not used to writing them in english :) Hope you will understand anyway.
Object number 1 is moving horizontally (left to right) with Uniform rectilinear motion at the speed of 10.5 m/s. Its mass is 7.5 Kg. The coefficient of dynamic friction is 0.15. A drawing force drags object number one from left to right (with an angle of 45) and its vertical component(projection) has the same value of its horizontal component, which is 9,6N.
Evidently the frictional force is -9,6N, otherwise the motion would not be uniform rectilinear.
Now Object number 2 (same mass of number 1, 7.5 Kg) falls on object number 1 vertically, causing a perfectly inelastic collision and it stays attached to object number 1.
The drawing force stays constant (it doesn't change from 9.6N vertically and 9.6N horizontally).
what is the speed right after the collision?
what distance does the object number 1+2 cover before it stops?
Thanks for the help.
