Newton Third Law problem. Help pleaseee!
The 1.0 kg block is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is uk = 0.370.
What is the acceleration of the 2.0 kg block?
Manipulations of F=ma.
I have given this two tries.
First try,
Fx=Fa2-Fk2-Ft+Fk1=ma
20N-(0.370)(3.0kg)(9.81m/s^2)-3.63N+(0.370)(1.0kg)(9.81)=3a
and I get it wrong..
