1. The problem statement, all variables and given/known data Two blocks of mass m1=80 kg and m2=100 kg and attached by a string, another sting comes off of mass m1 and is pulled horizontally (kinda looks like this) (T1 & T2 are tensions) m2--T2--m1--T1--> there is a coefficient of friction u=.14 for both blocks, what is the tension in both strings while the system accelerates at 2 m/s^2? 2. Relevant equations Fnet=ma Ff=u(N) 3. The attempt at a solution Ok so for m1 horizontal forces are T1 to the right, T2 to the left and friction. T2=(100)(9.8)(.14)=137.2 N Friction for m1=(80)(9.8)(.14)=109.8 So T1-T2-Ff = m1*a therefore T1=(80)(2)+(109.8)+137.2= 407 N Is this Correct?? Thanks!
