Question

Please show all the small steps in your process, even if it seems like the way you got from one step to another is obvious. I don't know how to set it up, so please include why you have set up the problem the way that you have (as in, how do you know to do it the way that you do?). Thank you!

Blocks with masses of 2 kg , 4 kg , and 6 kg are lined up in a row on a frictionless table. All three are pushed forward by a 56 N force applied to the 2 kg block.

Answer 1

56 N 2kg+ 4kg + 6kg the acceleratino of all t he masses combined,a- - 4.6667 m ml+ m2+ m3 partA) the force of 4kg block on 6kg= 6kgx 4.6667 m / s-28.0 N partB) the force of 4kg on 2kg whichisthe reaction force is the same as the action force of 2kg on 4kg F(4kg 2kg)--F(2kg -4kg)-(4kg+6kg). 4.6667 m/s 46.667 N
