Thank you for trying, those are the exact questions they asked me. So yeah...I need answer for the 2nd part of question #1, and confirmation of #2...
Would greatly appreciated if someone can help me out before midnight, 1h 30min left.

Homework Equations
F= maThe Attempt at a Solution
Fnet=m1a
T= M1a
Fnet=m2a...
Hmm, ok so now i got this.
m1:
Fnet=m1a
Fapplied-T-Ff=m1a
m2:
Fnet=m2a
T-Ff=m2a
a=T-Ff/m2
plug a into m1's equation
Fapplied-T-Ff=m1(T0Ff/m2)
53-T-(0.30x4.0x9.8)=4.0(T-0.30x7.5x9.8/7.5)
53=1.53T
T=34.565N = 35N
If someone can check if i did the calculation right, it would...
1. Homework Statement
Two blocks (m1=4.0kg, m2=7.5kg) are attached by a light cord pulled along a horizontal surface by a force of 53N as shown in the diagram. If the coefficient of friction between the blocks and the surface is 0.30, what is the tension in the rope between the two blocks...
