(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The constant force that works in the object M=5 kg forces the object with mass m=4 kg to move with acceleration a=2 m/s^2.

The coefficient of friction between M and the table is 0.2.

Determine

a)F=? b) T=?

2. Relevant equations

3. The attempt at a solution

SOLUTION:

F-Ff=(m)*a Here I find F

and here I find F

B) F-(T+Ff)=m*a or T=m2*g ;G-T=m*g

Edited: Maybe it is F-Ff=(m+M)*a where Ff =M*g*0.2?
